<center>CP Heat Calculation Handout 2</center><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> 1. What is the specific heat (c) of a substance if the 82.3g of substance released 1985cal of energy while the temperature went from 74.3°C to 21.0°C? (0.453cal/(g-°C)) system __________<br> <br> <br> <br> <br> <br> <br> <br> <br> 2. A container of water gains 532cal of energy and the temperature went from 28.2°C to 39.1°C. How many grams of water is there? (g or g ) system: __________<br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> 3. What is the temperature change (ΔT) of water if the water released 3020J of energy for a mass of 21.1g of water. (-34.2°C) system: __________<br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br>
