South African Analytical Chemistry student here🇿🇦 Your videos have been of great help👌Your explanations are not complex and fully understandable. Thank you very much!!
The gas expands after getting energy. So, the gas is not losing energy during expansion. Rather, it is getting energy. It is a natural law that an object expands on getting heat energy and contracts on losing heat. I am baffled ........ !
For a gas that is in contact with the surroundings, that is possible. But we also speak of an adiabatic expansion (or compression) in which a gas is completely insulated from the surroundings so that no heat can be transferred in or out of the system. So if a gas expands adiabatically, it can't get the energy needed from the surroundings, but rather must obtain the energy from itself. This is evidenced by a drop in temperature upon expansion which reflects a lower average kinetic energy of the gas particles after the expansion. Hope this helps!
