Does a compressor make cold or remove heat?

A compressor removes heat. Cold is the absence of heat. In the winter, a heat pump removes heat from the cold air outside and puts it inside. A refrigerator moves heat from in to out.
An automotive air conditioning system can be split into two parts, a high-pressure side and a low-pressure side. The engine-driven compressor compresses the gas, sends it through the condenser where it gives off heat, condensing and changing state to a liquid, gets filtered through the drier, then passes through the expansion valve which atomizes the refrigerant and turns it into a stream of cool, low-pressure droplets. This vapor travels through a heat exchanger in the passenger compartment of the car and sucks the heat out of the air, then is sent back to the compressor again.

the compressor compresses a gas so it gets hot, then sends it through a radiator so it cools off, and then lets it expand again so at that point it is colder than before it was compressed. so then it can go through another radiator to cool the what ever is around that off more than the surrounding air.
In you refrigerator for instance you have a radiator outside it, usually in back or underneath, to get rid of the heat of the compressed gas, so when it expands again inside it will keep the refrigerator cold..

Cold is the absence of heat, i.e removing energy from a system.

You can't make cold, only remove heat. So... the second option.

Cold is only the absense of heat so the second

the absence of kinetic energy at the atomic or molecular level. a compressor would tend to increase density per area so, logically would increase temperature, even if you were compressing liquid nitrogen.please, look up BOSE-EINSTIEN CONDENSATION, i am sure you would find this most interesting

SOME INERT GASSES UNDER COMPRESSION GET EXTREMELY COLD THEY DON'T REMOVE HEAT AS MUCH AS THEY LOSE HEAT

When Pressure decreases, temperature decreases, and when pressure increase, temperature increases.

when you comress air it gets hotter but when it expands it gets colder. thats y the gas in the sun is so hot, its squized so much it fuses
