foundation Specific wake up is defined as the measure of the ability of a substance to change temperature. Specific heat of a substance is the heat needed to change the temperature of 1 gram of a substance formerly degree Celsius. The more Joules (unit of heat) needed, the higher the specific heat allow for be. The polish is to determine specific heat of a stigma sample as compared to water. This oddment has many ramifications regarding our climate, with local and global. HypothesisI predict that after 10 legal proceeding of being placed at a lower place the same heat lamp, the dirt will suck heat flyinger, therefore ending with a higher temperature than the water. Materials 2 petri dishes Soil Water 2 thermometers Heat lamp Procedure 1. Design research laboratory tables. 2. book mass of petri dish and then add enough soil to fill it to the brim. Record mass again. The difference is the mass of the soil sample. 3. Record the mass of another petri dish and fill it with wa ter. Record the mass again. The difference is the mass of the water. . Place the thermometers so that the bulb of one is beneath the mount of the soil and the bulb of the other is under the water. 5. Place both samples under a heat lamp, making sure the thermometers stay under the samples. diddle the lamp close to the petri dishes so that they are heated equally. 6. Record the temperature of each thermometer all(prenominal) 30 seconds, for 10 minutes. 7. Graph your temperature data on the same redact of coordinates.

The remaining 6 minutes, the soil leveled out at a temperature of 25 degrees. While the soil continued to heat up at a relatively fast rate, the water do very small increments of progress and eventually made no advancement heating. Conclusion The hypothesis predicting that soil will absorb more heat than the water has been proven correct by the preserve data. My results showed that the temperature of the soil sample increased 2. 5 degrees Celsius, while the water except raised one degree.
