Q6// A heat pump is used to maintain a house at 22°C by extracting heat from the outside air on a day when the outside air temperature is 2°C. 22°C The house is estimated to lose heat at a rate 5 kW of 110,000 kJ/h, and the heat pump consumes HP 5 kW of electric power when running. Is this heat Outdoors 2°C pump powerful enough to do the job?

First law of Thermodynamics

The word thermodynamics consists of two words: thermo- and dynamics. Dynamics means the study of motion. The field of thermodynamics is all about the study of the movement of heat. In a more meaningful way, it is stated as the study of the transfer of energy. Energy transfer is something that we encounter in day-to-day life. Automobiles, chemical reactions, refrigerators, and power generators work on the basis of thermodynamic principles.
