What is the amount of heat (kJ) required if 64.0 kg of H2O is heated from 25°C to 85°C? 200.0 g Al (C = 0.900 ) at 95°C is added to 85.4 g H2O at 25°C. What is the final temperature of the water (and the Al)? 500.0 g ethyl alcohol at 25°C (C = 2.46 J/g x °C) absorbs 74.0 J of heat energy. What is the final temperature?
