Refrigerants used in fridges, freezers and cars change from a fluid to a gas to transport heat away from the place you want cooled.
In refrigerators, the refrigerant starts as a liquid and expands into a gas, which forces it to cool down.
The refrigerant then flows through condenser coils where it releases its heat out and cools back into a liquid.
The cycle starts over when the refrigerant enters the expansion device, where the fluid spreads out, cools, and once again turns into a gas.
Methane, the second most important greenhouse gas after carbon dioxide is 28, or 28 times worse.
