A calorimeter was filled with 200 g of water. The temperature of the water in the calorimeter dropped from 55.0 °Celsius to 22.6 °Celsius. The specific heat of water is 4.184 J/g°C. Calculate, q, the heat released by the reaction.

A) -2710 J
B) -27,112 J
C) 18,911 J
D) 1891 J

How much heat is required to convert 0.3 kg of ice at 0°c to water at the same temperature

6–43 a food department is kept at 2128c by a refrigerator in an environment at 308c. the total heat gain to the food department is estimated to be 3300 kj/h and the heat rejection in the condenser is 4800 kj/h. determine the power input to the compressor, in kw and the cop of the refrigerator.

Need only answer if you think you know it
