Solid, liquid, and gas — these are the basic three states, orphases, in which the majority of small-molecule substances can exist. At most combinations of pressure and temperature, only one of these phases will be favored; this is the phase that is mostthermodynamically stableunder these con...
So the freezer becomes the coldest part of the refrigerator, where water turns into ice and food is frozen solid.Any warm air in the refrigerator rises towards the freezer and helps change the liquid refrigerant into a gas. The gas flows round to the bottom again,where the pump compresses(...
