I'm taking "Physics of the everyday" on Brilliant. Here is the diagram of how refrigerators work:
Regarding the cooling step:
After exiting the compressor, this gas cools to room temperature in the external radiator, maintaining its high pressure.
How can the gas cool down but still maintain its high pressure? Isn't the lower the temperature, the slower the gas molecules move which means less of a force exert on the container which in turns mean lower pressure?
