A Midsummer Night’s Dream: Worlds Collide Four worlds collide in a magical woods one night in midsummer in William Shakespeare's mystical comedy A Midsummer Night’s Dream. The mythological duke of Athens, on the eve of his wedding to the newly defeated Queen of the Amazons, is called upon by the mortal Egeus to settle a quarrel. Hermia, Egeus's vociferous daughter, refuses to marry the man her father has betrothed to her, the enamored Demetrius. Theseus sides with authoritarian Egeus and forces
Extremes Collide In My Name Is Asher Lev By Chaim Potok In My Name is Asher Lev, Chaim Potok writes about a young boy in a Landover Hasidic community in Brooklyn who is an excellent artist. Asher travels through childhood hanging onto his art, but when his art interferes with his religious studies, Asher's two worlds of art and Torah collide. Potok deliberately chooses the extreme icons and symbols of secular life, such as the world of art, on the one hand, and of Judaism, Hasidim, and the
predict that the greater amount of concentration the faster the reaction will take place. Therefore, particles in the two compounds will collide faster. Due to my prediction if it is correct, I expect to see the cross on the paper disappear faster. As I already know that increasing one quantity will speed up the reaction as the particles are more likely to collide. In this investigation several measures will need to be done to make sure that the results I get will be precise. From the planed method
collisions between the particles therefore the reaction is speeded up.) * Temperature of Water-°C. (As the temperature increases so does the rate of reaction. By increasing the temperature, particles move faster, i.e. they have more energy. So, they collide with more energy and more frequently.) * pH of Solution: Water has pH of 7 at 25°C. As the pH decreases, i.e as the solution increases in acidity, the rate of the reaction increases as well. Output Variables: ----------------- Rate of
there is less space in which to move and so the particles are more likely to collide each other. Using a catalyst is another method I could use. A catalyst is a substance, which lowers the activation energy of a reaction without being chemically altered. Energy. By giving the particles extra energy, as heat, they will move faster. This means that they cover more ground and are therefore more likely to collide with each other which in turn makes the reaction faster. (We have to take into
will then make the reaction taking place speed go slow, so there would be a graph with a rather slow reaction taking place. If I was to do the experiment with a high concentration the particles are crowed close together and therefore it would collide with each other more often, which will give me a result of successful collisions. So for my experiment I predict that the concentration would be high with successful collisions. Different potatoes may have different concentrations of enzymes; if
and substances. I have chosen to investigate Temperature. I predict that the higher the temperature the more rapidly the cross would obscure. This is because the higher the temperature the more often the particles collide and react, when the particles collide more often they would collide harder because they have more energy, making the collisions bigger and faster, the collision success rate is higher. I will make my investigation a fair test by keeping the quantities of the Hydrochloric acid at
extension to the kinetic theory called the collision theory. The collision theory says that Chemical reactions occur when particles of the reactants collide. They must collide with a certain minimum energy, called the activation energy. To summarise, the requirements for an effective collision (for a chemical reaction to occur): The reactants must collide with each other, The molecules must have sufficient energy to initiate the reaction (called activation energy). Planning This experiment
cannot be changed back to its runny state. When proetin of an ezyme is denatured it no longer functions as a catalyst. COLLISION THEORY 'Rate of reaction simply depends on how hard and often the reacting particles collide with each other.' The basic idea is that particles have to collide with each other in order to react. MORE COLLISIONS INCREASE THE RATE OF REACTION. 1) Temperature increases the number of collisions. 2) Concentration (or pressure) in creases the number of collisions. 3) Sizes
amount of zinc each time, use the same conical flask and gas syringe. Background ========== This experiment is showing the effect on the rate of reaction between zinc and sulphuric acid if you change the concentration. To react, reactants must collide with enough energy to result in successful collisions. If you increase the concentration, then that means that there are more particles in the same volume to react. Therefore, there will be more successful collisions per second. If there are more
Wire Introduction: In this piece of coursework, I have been finding out factors that affect the resistance of a wire. Firstly, I will explain how resistance works. Resistance is when electrons in a wire collide with atoms also in the wire. When the electrons and the atoms collide the electrons start to move slower, which then causes resistance. So, resistance is how hard it is to move electrons through a wire. Now, I am going to tell you what are the factors of wire resistance. Number
In a reaction, particles of two different reactants react together to form a product. The reaction only takes place on account of two things, if the particles collide, and if the collision has enough 'activation energy'. The two reactant particles, in this case magnesium particles and hydrochloric acid particles, must collide with each other on the correct 'collision course'. If this does not occur then no chemical reaction will take place. The reaction must also have enough energy, this
(resistivity) The factor I shall investigate is the length of a wire. Background Knowledge Resistance is when electrons travelling through the wire are impeded by the atoms within the wire. Since the electrons are charge carriers when they collide with the atoms in the wire less pass through. There fore less current passes through with the same voltage. Simply it is how hard it is for the electrons to pass through the wire. Temperature: When the metal wire is heated , more energy s
The greater the surface area, the faster the rate of reaction. This is because more atoms are exposed and ready to react. The higher the temperature, the faster the rate of reaction. This is because raising the temperature makes the particles collide more often in a certain time and it makes it more likely that collisions will result in a reaction. Catalysts speed up chemical reactions therefore increase the rate of reaction. The collision theory is that the more collisions between particles
molecules through a hole that is smaller than the mean free path, which is �the average distance [a] particle travels between collisions with other particles� (�Mean free path�). This means that in effusing through the hole the gas molecules do not collide with one another. ef�fu�sion �noun One of the postulates of the Kinetic Molecular Theory states that average kinetic energy of gas particles depends solely on the temperature of the gas. Since this is the case, the kinetic energy of two gas molecules
that that the different particles need to collide with each other in order to react. However, they do not react if they collide without sufficient energy, and therefore the more energy a particle has, the more likely it is to react. The activation energy is the minimum amount of energy required by a particle in order to react. When a rate of reaction is improved, the likelihood of the collision of particles is higher and the energy at which they collide is increased. The importance of rates
Temperature When the temperature of a reaction increases, heat is supplied to the particles of the reactants involved. This heat energy is converted into kinetic energy which all of the particles acquire. This means that more particles collide with each other per second. In addition, the faster the particles are travelling, the greater proportion of them which will have the required minimum energy for reaction to occur, for example, raising the temperature of a reaction by 10°c will
Mars and Jupiter once existed and after many years it exploded into thousands of pieces that are still revolving around the sun in the form of an asteroid belt. Other asteroids are formed when large meteors collide with large asteroids creating more small ones. These meteors can also collide with planets breaking off chunks of the crust into space. Ceres is believed to be the biggest asteroid that was in space at one point in time. Ceres was believed to be 600 miles wide, making up 1/3 of the total
concentration or more volume there is of an acid, the more acid molecules there are that can react with the chalk. The larger the surface area of a solid, the more surface there is for acid to collide with and react with. Higher pressure pushes the molecules closer together, so it's quicker for them to collide with each other and therefore react (so raising the pressure is like raising the concentration). Every reaction needs a little "activation energy" to make it happen, and when catalysts are
Rates of Reaction Investigation Reactions happen when the reactant particles collide and turn into a product. Sodium and chlorine, when reacted, they give us a compound Sodium Chloride (salt). Chemical reactions can be very difficult to undo. When metal rust this is a slow reaction, however burning, this is very quick. A speed on which the reaction takes place is called and rate of reaction. There are many ways on which to speed up the reaction. The most common is to speed up the collision
