Homework Answers
heat capacity: it the amount of heat energy needed to increase the temperature of 1 kg mass by 1 kelvin.here 5 kj heat energy needed to increase the temperature of 1 kg mass by 1 kelvin.so the heat capacity is 5 kj/kg-k.

The amount of heat needed to raise the temperature of 1 mole of a substance by...
The amount of heat needed to raise the temperature of 1 mole of a substance by one Celsius degree (or, equivalently, one kelvin) is called the molar heat capacity of the system, denoted by the letter C. If a small amount of heat dQ is put into n moles of a substance, and the resulting change in temperature for the system is dT, then C=1ndQdT. This is the definition of molar heat capacity--the amount of heat Q added per infinitesimal...
Specific heat is the heat necessary to raise the temperature of 1kg of a given material...
Specific heat is the heat necessary to raise the temperature of 1kg of a given material by 1∘C. This specific heat value varies by material with metals having relatively low specific heat with organic materials and water being very high. The specific heat of mercury is 140 J/kg∘C and the specific heat of water is 4190 J/kg∘C. 1.140 J of heat energy are transferred to 30.9 g of mercury. By how much does the temperature increase in Celsius? 2. How...
