How are the terms energy and work related

WebHeat flow Q ˙ has an associated entropy flow Q ˙ / T. The job of a thermodynamic engine is extract/filter as much useful work as possible from a flow of energy and entropy. To answer your question in layman terms. Work is entropy free energy, it is what you have managed to extract/filter from a flow of heat by rejecting entropy. WebFor solids and liquids. cp = cv (1) The specific heat represents the amount of energy required to raise 1 kg of substance by 1oC (or 1 K), and can be thought of as the ability to absorb heat. The SI units of specific heats are J/kgK (kJ/kgoC). Water has a large specific heat of 4.19 kJ/kgoC compared to many other fluids and materials.
