Heat Capacity of Water

Heat Capacity of Water

Requirements

The materials that were used to test in this project includes sand, water, salt,oil,soil and tape.

Method

Take a container place a material inside it along with a two thermometer, one at a depth of two centimeter each and another on the surface. Now turn on a lamp for one hour. Place this lamp at a distance of few centimeters over a material. Check temperature for every five minutes for each thermometer. After a completion one hour of time span turn off the lamp. Again record the temperature for every five minutes. It was conducted in three intervals for each material.

Results

After analysing the test results it was evident that the soil was loosened when it absorbed heat and moreover it did not absorb much heat compared to other materials that used in this experiment. The water absorbed a little amount of it but it was not released, it kept in it. The oil absorbed a lot of heat compared to other materials and it ended by losing lots it but not at the rate of earth materials.

Conclusion 

This working science model for class 10 illustrates different types of materials absorbs and releases heat. By this one may try to make climate prediction. Suppose if your are staying in a city beside the beach, It will definitely have a good weather as water keeps the heat. Weather over there is neither too hot or too cold.
