ways by which people live their lives or how society behaves. Some characteristics of the culture of people or a society are their music, food, laws, arts, marriage, festivals among others. Ghana is the first sub-Saharan African nation to gain its independence from the British in 1957. It is located in West Africa and it consists of different ethnic groups with different dialects. One such group is the Ga-Adangbe tribe. The Ga-Adangbe tribe constitutes of the Adangbe and the Ga people of Ghana who
breathing in the human body. The gas law, Charles’ Law, demonstrates the relationship between a contained volume of gas and its temperature, a directly proportional relationship. It states that in a contained space, if a gas’ temperature were to increase, the volume of the gas would increase as well (Colbert, et al., 2012). Charles’ Law is confirmed every day inside and outside a hospital, and it is especially important to understand when working with the human body. Most people, at one time or another,
racks * Gas Syringe (200ml) * Stop Clock [IMAGE] [IMAGE]Method: In a preliminary study, I found the best way for me to do this experiment is by measuring 10ml of distilled water into a measuring cylinder, and mixing glucose solution and yeast suspension. I am going to keep the volume and concentration of the glucose and yeast the same, but the only factor I am going to change is the temperature. Then we put the bung on to the test tube leading to the gas syringe.
Fuel For A Paintball Marker The Reason that people need a tank when they play paintball is because you need a way to force the paintballs out of the gun and this cannot be achieved effectively by just using a spring. What they decided to do was to fuel the paintballs by pushing them with a gas. The way in which they did this was to put the gases, either Oxygen, Carbon Dioxide or Nitrogen under extreme pressure until they turned into a liquid and once they are in a liquid form they can be blown
John Harte is an ecologist from the University of California at Berkley. He is trying to find out whether heat stimulates further trace-gas from solid or not. He is going to conduct an experiment that will tell him if the greenhouse effect could start a cycle that would cause the effects to be worse than already predicted. The experiment will begin December of 1996 and will run for no less than three years. Harte has stretched a twelve foot high grid of cables above 300 square yards of land
Rate of Reaction Using Enzymes In this bit of coursework I will be investigating the rate of reaction in which enzymes are the catalyst breaking down a substrate. The substrate I am going to use is Hydrogen Peroxide (H2O2, water with another Oxygen), this molecule usually breaks down on its own accord, but also the rate of decomposition can be increased with the use of a catalyst; in this case the catalyst is a biological one called an enzyme. Hydrogen Peroxide slowly breaks down on its
Science Rocket Experiment By : Julia Sánchez Background Information: This experiment is about firing a rocket, we are creating hydrogen gas. We had to fill the bottle with hydrogen gas and then put a flame under the bottle and measure how much it flew upwards. To do this we mixed magnesium strips into hydrochloric acid. A combustion reaction takes place in this experiment. The investigation topic is about the fuel that makes a space rocket fire. A combustion reaction is more known as burning
The two articles, As the World Burns and Why Bother, both discuss the challenges of what individuals faced with trying to help stop global warming. In Why Bother, the author explains why one individual would not want to bother changing the climate change, if the entire universe is not going to change as well. However, in As the World Burns, one of the little girls is trying to persuade her friend to go greenhouse friendly but the friend doesn’t by any of what her friend is trying to tell her. The
scientific method, Joseph Louis Gay-Lussac earns the title of a great scientist. He was born on December 6, 1778 and he was the oldest child. His father was Antoine Gay. He was a lawyer who called himself Gay-Lussac to be apart from all of the other people with the same last name as Gay there. He got that name from the name of some family property near St Leonard(4) . The French Revolution affected the French scientists then. Gay-Lussac was sent to Paris when he was fourteen when his father was arrested
was and still is a very important person. He received an honorary degree from the University of Oxford. He was also elected into the Royal Society of London and of Edinburgh. He was very well known when he was alive. After his passing, over 40,000 people showed up to his funeral. His contributions to science were so important that without them we would not be technologically where we are today. Works Cited “Dalton, John (1766-1844)”. Wolfram Research. 2007.

to each shown in (Figure 1). When Benzene was first discovered it was called hydrocarbon. The chemical that we now call Benzene was discovered in 1825 by Michael Faraday. Michael Faraday discovered Benzene from an oily film that deposited from the gas used for lighting. Benzene has a great effect on the environment and health though exposure and effects may vary depending on the life style of a person. The physical properties and chemical properties are essential to a chemical compound, these
Measuring Viscosity Aim - to determine how the mass of Corn flour added to 100ml of water affects the viscosity (gooeyness) of the final mixture. Background - Corn flour, when added to water increases its gooeyness of viscosity. Although this value cannot be actually measured, a person can determine a rough value of its viscosity by recording how long an amount of the mixture takes to flow from one receptacle to another. The longer it takes to flow, the more viscous the mixture. The
Investigating How Quickly Amylase Breaks Down Starch With Varying Temperatures Instructions List I gathered the equipment shown below. I put 3 drops of iodine in each chamber of the spotting tile. I boiled the kettle and mixed together water from the kettle with water from the tap so the water reaches the correct temperature. The water was put into a beaker. 5ml of starch was put into a test tube. The test tube was placed into the beaker. When the water in the beaker was at the required
The Effect of Temperature on the Rate of a Reaction Aim and Hypothesis The investigation that we have chosen to do is how the effect of temperature affects the rate of reaction of hydrogen peroxide to water and oxygen using the enzyme catalase. I predict that the higher
.to the left. This occurs because the rate of the reverse reaction is greater than the rate of the forward reaction when the volume of the system is decreased and the pressure is increased. (e) There is no change in equilibrium when an inert gas (noble gas, therefore outer valence shell is full, making the molecule very stable) is added to the reaction without changing the volume, since the amount of reactants and products does not change.

the column, it is observed that the degree of foaming becomes more violent and more spread out. When the pressure drop is relatively high, it means that the pressure exerted by the vapour is insufficient to hold up the liquid in the tray, causing the gas bubbles to appear on top of the sieve trays. To add on, the higher the pressure drop, the higher the velocity of the vapour passing up the column. As a result, more vapour will penetrate the liquid and more bubbles formation is observed. Due to more
The general properties of fluids are density, specific weight, viscosity and relative density. The values under specific conditions (temperature, pressure, etc) can be readily found in many reference books. But in this experiment, we want to measure the fluid properties by using instruments and compare the measured values with the theoretical values. In this evaluation of fluid properties experiment, we will measure two fluid properties, which are, density and viscosity. Selected fluids were used
Recrystallization is a common technique used for purifying an impure compound within a solvent. This method of purification is based on the principle that the solubility of most solids increases with higher temperature. For this type of purification, an impure compound is first dissolved to prepare a highly concentrated solution at a high temperature. Following this the solution is cooled, which drops the temperature and causes the solubility of the impurities in the solution, along with the substance
Material science LO2 Quenching Quenching is heat treatment process, the material is rapidly cooled of workpiece to obtain certain material properties. low temperature processes, such as phase transformations, from occurring by only providing a narrow window of time in which the reaction is both thermodynamically favourable and kinetically accessible. It increases hardeness of both alloy and plastics and reduce crystalliity. Effect of quenching The structure of material before
dropped. The first relationship is called Boyle’s Law and was originally found by Robert Boyle, who published it in 16621. This law is now used to carbonate sodas. By pressurizing soda cans, the CO2 gas inside it is forced to dissolve, and when the can is opened, the pressure is relieved, and the gas begins to
