Which Heats Up Faster; Sand or Water? Essay Example
Question: Which heats up faster: sand or water?
Hypothesis: Sand heats up faster than water because it has a lower specific heat. Water has a specific heat, which requires one calorie of energy to raise the temperature of one gram of water by one degree Celsius. Sand has a lower specific heat. It takes .19 calories per gram to raise the temperature of the sand by 1 degree Celsius. Sand requires fewer calories to raise its temperature one degree Celsius and that’s why it heats up faster than water.
Experiment: See lab sheet. In this experiment there was no control. The independent variables in this experiment are the time, and the amount of sand and water put into the cans. The dependent variable is the degrees (in Celsius) that air, water, and sand get to. The time, and amount of sand and water is the independent variable because it does not have to rely on anything. The degrees (in Celsius) that air, water, and sand get to is the dependent variable because it relies on the time and amount of sand and water (put into the cans).
Analysis: In the experiment the first thing done was the gathering of the materials. The experimenter got one lamp, one lampstand and attached them together. Then got three cans of the same color, shape, and size. The experimenter went to a bag of sand and filled the can ¾ of the way. Then went to the sink and filled a different can ¾ of the way with water. After all the cans were filled to the same amount the experimenter placed the three cans together in a triangle shape. Then went to get three thermometers. Returned to the cans and placed one thermometer in each can. The experimenter then looked at the temperature for each can and recorded it as the original temperature. Air’s original temperature is at 23° C. After five minutes the temperature was at 36° C. Ten minutes the temperature was at 38 ° C which was the same for the next fifteen minutes. At thirty minutes the temperature was at 40 ° C. The experimenter then
