What Affects the Rate of Evaporation in Different Liquids

Use ice if you need to. Then, fill one beaker with 175 mL of water and the other with 350 mL. Warm the water in the 350mL beaker up to 55 degrees celsius and cool the water in the 175mL beaker to 15 degrees celsius, the same temperature as the pitcher because it will be your control group. Once the beaker that should be heated is at 55 degrees celsius, pour 175 mL of the water into a glove and pour the other 175 mL into a ziplock baggie. Pour the 15 degrees celsius, 175 mL of water into another ziplock baggie. Before you set these in water, have a stopwatch ready and make sure that the water in the baggies and glove is at the right temperature.

The dependent variable in the experiment was the temperature and energy absorbed by the water.

Step 2: Place a saucepan with tap water on a burner and bring to a boil.

Procedure: Using distilled water, premeasured containers and objects determine displacement of fluids and density of objects. Use ice and heat measure temperatures in Celsius, Fahrenheit and Kelvin.

27. Heat the water to 40°C with an alcohol lamp by setting up the apparatus as shown in figure 3 below:

1. Move the lid of the container up or down. Record the resulting volume and pressure

The aim of the experiment will be to investigate how varying water temperatures influence the time of a chemical reaction, in this case being, a combination of Sodium Thiosulfate and Hydrochloric Acid.

Place the beaker on the hot plate, place the thermometer in the beaker and set the hot plate to 5oC.

Another potential error, which might have occurred, is the temperature fluctuation throughout the experiment. The rate of osmosis will be affected if the temperature in inconsistent, as more heat increases rate of osmosis and cooler temperature decreases rate of osmosis.

9) Trial E: Remove the syringe and empty the beaker. Add a Thermometer to the beaker. Add 200 mL of Room Temperature water to the beaker and heat with a Bunsen Burner until it reaches 100° C. Remove the Bunsen Burner. Repeat Steps 5 & 6.

Fill a test tube about 1/3 full with cold tap water for use in step 34.

Abstract: This experiment introduced the student to lab techniques and measurements. It started with measuring length. An example of this would be the length of a nickel, which is 2cm. The next part of the experiment was measuring temperature. I found that water boils around 95ºC at 6600ft. Ice also has a significant effect on the temperature of water from the tap. Ice dropped the temperature about 15ºC. Volumetric measurements were the basis of the 3rd part of the experiment. It was displayed during this experiment that a pipet holds about 4mL and that there are approximately 27 drops/mL from a short stem pipet. Part 4 introduced the student to measuring

4.Measure 35mL of warm water and add them into each of the 4 test tubes at about roughly the same time. It is essential that the water is warm. Do not seal the test tube.

This experiment was used to examine the hypothesis that: Osmosis is dependent on the concentrations of the substances involved.

Add 2 drops of soap to the removed test tube, and place it in the test tube holder.
