The Effect of Temperature on an Increasing Volume of Water
Aim:
To observe the effect of temperature on an increasing volume of water.
Apparatus:
* Stopwatch
* Thermometer
* Beaker
* Bunsen Burner
Method:
* Fill a Beaker with 50cm3 of water
* Heat the water over a Bunsen flame for two minutes, using a
stopwatch
* After two minutes, take the temperature of the water using a
Thermometer
* Repeat the experiment using an extra 25cm3 of water
Before we began the experiment, we used a trial method to determine
how long we should heat the water; heating 50cm3 of water first for 1
minute, then 1 minute 30, and finally 2 minutes. We decided to use 2
minutes, as this gave the best results.
We repeated the experiment fifteen times, firstly heating 50cm3 three
times, then adding 25cm3 of water each time, so from 50cm3 to 350cm3.
After each repetition we rinsed the beaker so as to make this a fair
experiment.
The variables in this experiment were Volume and Temperature. So as to
make this a fair experiment, care was taken to ensure that the beaker
was rinsed every time, and that the thermometer was at room
temperature, so as not to yield any anomalous results. All the results
will be taken on the same day, so that the room temperature does not
differ, as this could affect the results also.
My Hypothesis:
My Hypothesis is that the temperature of the water will decrease as
the volume increases.
Analysis Of Hypothesis:
This is because, as the volume increases, the particles in the water
are more spread out. They will be using more energy, but fewer
collisions will be occurring, resulting in a lower temperature.
Results:
The results of my experiment are presented as both a table and a
Two equations were used in this experiment to determine the initial temperature of the hot water. The first equation
The researcher conducting this experiment is trying to find out which salt- Epsom, table salt, and sea salt- will increase the boiling point of water the most. Sodium chloride is believed to increase the boiling point of water because when salt is suspended into the water, the sodium and chlorine ions leave the “salt crystals” and mix with the water molecules. (“Why does salt… raise boiling point of water?”, 2009).
When the amount of hot water released and cold water absorbed do not coincide, then it means the calorimeter is absorbing some of the heat. The amount of heat that is actually released depends to the mass, specific heat of the substance, and the change in temperature.
The Effect of Solute Concentration on the Rate of Osmosis Aim: To test and observe how the concentration gradient between a potato and water & sugar solution will affect the rate of osmosis. Introduction: Osmosis is defined as, diffusion, or net movement, of free water molecules from high to low concentration through a semi-permeable membrane. When a substance, such as sugar (which we will be using in the experiment we are about to analyse), dissolves in water, it attracts free water molecules to itself, and in doing so, stops them from moving freely. The effect of this, is that the concentration of (free) water molecules in that environment goes down. There are less free water molecules, and therefore less water molecules to pass across a semi-permeable membrane, through which sugar molecules and other molecules attached to them are too big to diffuse across with ease.
Osmosis Experiment Planning Aim: The main subject that I will be planning to investigate is the effects of a concentrated sucrose solution on potato cells on the basis of the Osmosis theory. Background knowledge: The plant cell and its structure To understand osmosis in detail I will need to explain the plant cell (which is the cell included in the osmosis experiment) and its cell membrane. Below I have a diagram of a plant cell: [IMAGE] Osmosis is about the movement of particles from a higher concentrated solution to a lower concentrated solution to create an ethical balance via a partially or semi permeable cell membrane. Osmosis in simple terms is the exchange of particles between the cytoplasm inside the cell and the solution outside the cell. What makes this exhange is the partially permable cell membrane.
Over the observed fifty seconds, there was a consistency among the temperatures. Without a calculated percent error, we are able to assume the average temperature was twenty-six degrees Celsius. There are factors that could have caused error to arise in our data collection. One factor could be that the temperature of the room was not consistent throughout the room. Another factor may have been the performance of the thermometer. The grasp in which the thermometer was held for procedure B may also be a factor.
Volume's Effect on a Copper Sulphate Solution We are trying to find out if the current though a copper sulphate solutions volume is increased. To find this information out I shall perform an experiment using the following equipment; · 1 power pack · 1 beaker · 2 carbon rods for anode and cathode · 1 ammeter · 1 measuring cylinder · 2 crocodile clip wirers I shall also be using 60cm3 volume of copper sulphate in my preliminary results to decide upon the concentration of copper sulphate and the voltage I shall use. The following diagrams show the step by step process in which I will do my experiment; [IMAGE] [IMAGE] [IMAGE] [IMAGE] I will take 10 readings from 10cm3 to 100cm3. I will repeat my experiment to give my experiment a fair average. I will keep the power pack the beaker the carbon rods the crocodile clips the ammeter the concentration of copper sulphate and the measuring cylinder the same each time I do the experiment this experiment.
One of the experiments on trip was to test how fast the water was moving. Our group stood in nine different locations and did the testing. My hypothesis was if the water is deeper, then the water velocity will be faster. After the group did that, the group collaborated results, giving people the other answers so they can fill in their data sheet. Now the results will vary depending on what group you are in, and it can vary from all of us walking in and around the creek. As you can see on the left is the graph of all the data. The scatter plot indicates that my hypothesis is incorrect because if you look at it as the depth gets deeper, than the speed or velocity of the water goes down.
Variables --------- During the experiments, the water will be heated using different spirit burners containing different alcohols. I will be able to change different parts of the experiment. These are the. Volume of water heated:
The purpose of this experiment is to try to find the original temperature of the hot water in the heater using the 60 degrees C thermometer. Use your 60°C thermometer, and any materials available in your laboratory, to determine the temperature of the water in the coffee pot. During this experiment we calculated the original temperature of a heater after it had been cooled down, and we did this by measuring hot, cold, and warm water, with a thermometer that had tape covering 60 degrees and up. When preformed each of these experiments with each temperature of water, plugging them into the equation (Delta)(Ti – hot – Tf) T Hot x Cp x Mass(Cold) = (Delta)(Tf – Ti – Cold) T Cold x Cp x Mass(Hot)(d
- Temperature was measured after and exact time i.e. 1 minute, 2 minutes, 3 minutes.
After finishing the trials, our group subtracted the mass of the glassware without water from the mass of the glassware with water in order to find the mass of the water in grams. Then, we divided the mass of the water by the density(g/cm^3) of the water in order to find the volume (mL). An example calculation from the 5.00mL pipet is: (4.9285mL+4.8839mL+4.9367mL+4.9265mL+4.9134mL)/5 = 4.9178. In most cases, the temperature of the water was around 23 degrees celsius, making the density about .998408 g/cm^3 for many of the trials. The densities we used were found online. The next calculations we performed were to determine the average volume of the water in each person’s five trials by adding up all of the volumes(mL) and dividing that number by five. Using the average volume, we then calculated the
the mass of the potato cylinder as well as the length as the mass can
Evaporation is part of our everyday lives. After washing the dishes, after taking a shower, and many more signs of evaporation in our everyday lives, but does every type of liquid evaporate at the same rate? Sometimes liquids may be sitting in one dry place and its molecules might turn into gas molecules, that is the process of evaporation. When energy in certain molecules reaches a specific level, those molecules have a phase change. Evaporation occurs when molecules escape from their liquid and form into vapor. If there was a puddle of water outside, and it was a windy day, the air from the wind can cause an increased rate of evaporation. When a molecule
The water cycle also gets affected from human interaction with the environment. When we urbanized places we affect the ground water, which in turn affects the water cycle. Urbanizing areas and putting companies and gas station’s that produce waste is not good for the water cycle. The pollutants from these places seep into the ground and pollute the groundwater and make it harder for that water to come back to the surface clean. It takes years for this to naturally occur and when we interact with it like that it takes even longer and affects the cleanliness. The water cycle is constant and happens naturally without our involvement. So when we make it harder for the water cycle do keep itself running it is detrimental to the whole world.
