More Heat/Energy problems q = mCpT 1. How much water can be heated from 22.0°C to near its boiling point at 98.0°C, if 79.1 x 104 J of energy are added to it? The specific heat of water is 4.184 J/g-°C 2. Large beds of rocks are used in some solar-heated homes to store heat. Assuming the specific heat of rocks is 0.082 J/g-°C, calculate the amount of heat absorbed by 50.00 kg of rocks if their temperature increases by 12.0°C. 3. What would is the final temperature of the rocks from problem 2, if their initial temperature is 27.4°C and they release 450. kJ of energy? 4. What is the specific heat of iron metal, if 30.0 kJ of heat energy raises the temperature of a 1050. g block of iron from 25.0°C to 88.5°C? 5. The specific heat of ethylene glycol [anti-freeze] is 2.42 J/g-°C. What is q, if the temperature of 62.0 g of ethylene glycol changes from 40.8°C to 15.2°C?
