Calculate the energy transferred when a block of gold at 80.0°C is placed in a 2.00 liter (2kg) of
water at 25.0°C if the final temperature becomes 45.0°C. Specific heat of water is 4184 J/kg*C.

An engine runs on the ideal diesel cycle. the cycle has a compression ratio of 20 and a cutoff ratio of 2. the highest temperature in the cycle is 1200 k. if the heat into the system is 300 kj/kg of working fluid and using variable specific heats determine the work produced per mass of working fluid
