Specific Heat

Introduction Specific warmheartedness is defined as the measure of the ability of a substance to change temperature. Specific rage of a substance is the heat needed to change the temperature of 1 gram of a substance once degree Celsius. The more Joules (unit of heat) needed, the higher the specific heat will be. The goal is to determine specific heat of a flat coat sample as compared to pissing. This difference has many ramifications regarding our climate, with local and global. HypothesisI predict that after 10 minutes of being placed under the same heat lamp, the soil will absorb heat faster, therefore ending with a higher temperature than the water. Materials 2 petri dishes Soil Water 2 thermometers Heat lamp Procedure 1. Design lab tables. 2. Record mass of petri dish and then add enough soil to use up 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 water. Record the mass again. The d ifference is the mass of the water. . redact the thermometers so that the bulb of one is beneath the surface of the soil and the bulb of the other is under the water. 5. Place both samples under a heat lamp, make sure the thermometers stay under the samples. Bring the lamp close to the petri dishes so that they are heated equally. 6. Record the temperature of each thermometer every 30 seconds, for 10 minutes. 7. Graph your temperature selective information on the same set 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 recorded data. My results showed that the temperature of the soil sample increased 2. 5 degrees Celsius, while the water only raised one degree.
