WebWhen the hot gas in the coils meets the cooler air temperature of the kitchen, it becomes a liquid. Now, in liquid form at high pressure, the refrigerant cools down as it flows into the coils inside the freezer and the fridge. The refrigerant absorbs the heat inside the fridge, cooling down the air. WebNov 29, 2009 · "Thermodynamics is a branch of physics which deals with the energy and work of a system. Thermodynamics deals only with the large scale response of a system which we can observe and measure in experiments. Small scale gas interactions are described by the kinetic theory of gases.
WebAccording to the Second Law of Thermodynamics, heat will always flow spontaneously from hot to cold, and never the other way around. A refrigerator causes heat to flow from cold to hot by inputting work, which … WebFeb 2, 2024 · The third law of thermodynamics states, "the entropy of a perfect crystal is zero when the temperature of the crystal is equal to absolute zero (0 K)."
