<center>CP Heat Calculation Handout 1</center><br> <br> <i>Answer the following problems showing all work</i><br> <br> Equation: ΔH = (m)(ΔT)(c) Other equations m = c = ΔT = <br> ΔT = T<sub>F</sub> - T<sub>I</sub><br> where ΔH = energy flow/change of system<br> m = mass of system<br> c = specific heat of system _____________<br> T<sub>F</sub> = final temp<br> T<sub>I</sub> = initial temp<br> <br> <br> 1. How much heat (in cals) is required to raise the temperature of 155 grams of water from 25.0degC to 65.5degC?<br> <br> system __________<br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> 2. What is the mass of water if you added 3.4Kcal to the water and the water temperature raised from 63.2degC to 87.3degC?<br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> 3. What is the specific heat of a substance if the temperature of the substance is raised from 35.0degC to 98.3degC by adding 3.25KJ of heat energy. The mass of the substance is 365grams. <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> Answers:<br> 1) 6.28E3 cal<br>
