What is Difference between exothermic and endothermic reactions [in Table]

by

  Exothermic Reactions Endothermic Reactions Exothermic reactions release energy in the form of heat to the surroundings. Endothermic reactions absorb energy from the surroundings, usually in the form of heat. The overall energy of the system decreases as energy is released to the surroundings. The overall energy of the system increases as energy is absorbed … Read more

What are the steps through which a refrigerant goes in one complete cycle of refrigeration?

by

In one complete cycle of refrigeration, the refrigerant, a liquid such as fluorinated hydrocarbon, goes through the following steps : (1) The refrigerant in the closed tube passes through the nozzle and expands, into a low-pressure area. This adiabatic expansion results in reduction in pressure and temperature of the fluid and the fluid turns into a … Read more
