Convection and conduction.
In a refrigerator, energy transfers occur through the following processes: The compressor compresses a refrigerant gas, causing it to release heat energy into the surroundings. The high-pressure gas then flows through the condenser coils, where it releases more heat energy and condenses into a liquid. The liquid refrigerant flows into the evaporator coils inside the refrigerator, absorbs heat from the interior, and evaporates back into a gas. The gas is then sucked back into the compressor to start the cycle again.
You can use heat to change a liquid into a gas through a process called evaporation or boiling.
When you heat a liquid, it turns into a gas through a process called evaporation or vaporization. The heat increases the kinetic energy of the liquid particles, causing them to break free from their liquid form and become a gas.
convection
When the refrigerant leaves the compressor, it is in a high-pressure gas state. It then flows through the condenser coils, where it releases heat and condenses into a high-pressure liquid before entering the expansion valve.
liquid will make gas only if it is hot, because the heat will make it steam up making it a gas.
Convection is the transfer of heat by circulation through a gas or liquid.
Refrigerant in a cooling system absorbs heat from the air inside a space, turning from a liquid to a gas. The gas is then compressed, which increases its temperature and pressure. As the gas flows through the system, it releases the heat outside, turning back into a liquid. This cycle repeats, continuously removing heat from the indoor air and keeping the space cool.
Convection is the transfer of heat through the movement of a fluid, whether liquid or gas.
The transfer of thermal energy in a liquid or gas occurs through conduction, convection, or radiation. In conduction, the heat is transferred through direct contact between molecules. Convection involves the transfer of heat through the movement of the liquid or gas itself. Radiation is the transfer of heat through electromagnetic waves.
The transfer of heat through gas or liquid is known as convection. It involves the movement of the heated particles within the gas or liquid, which in turn transfers heat from one area to another. This process is important in various natural phenomena and in many engineering applications.
