Answer and Explanation
An electric devise which extracts heat from a point and transfers it to another is called a heat pump. Refrigerators and air conditioners apply this technology.
A heat pump circulates the refrigerant through an evaporation and condensation cycle to transfer the heat. A compressor then pumps the refrigerant substance between two heat exchanger coils. In one of the coil, the refrigerant undergoes evaporation at low pressure to absorb heat from the surrounding. The refrigerant then undergoes compression to follow the other coil where it undergoes condensation at high pressure. It releases the heat at this point that has been absorbed in the cycle.
Explanation:
Potential energy is the energy obtained by an object due to the position of an object. Whereas kinetic energy is the energy obtained by an object due to its motion.
For example, an ball is placed over a building of height h. Then steps followed to covert its potential energy into kinetic energy are as follows.
Step 1: When ball is at placed over a building of height h, then it has only potential energy and no kinetic energy.
Step 2: A man pushes the ball and it moves in the downward direction.
Step 3: When ball starts to move or fall it gains kinetic energy, that is potential energy now becomes equal to 0.
Similarly, on reaching the ground and after bouncing a few times when it stop moving then kinetic energy converts into potential energy.
