Thermal expansion is large for gases, and relatively small, but not negligible, for liquids and solids. Linear thermal expansion is ΔL = αLΔT, where ΔL is the change in length L, ΔT is the change in …

Why solids expand on heating - Physics Stack Exchange

WebWhen a system does work on the surroundings, the system's internal energy decreases. When a system has work done on it, the internal energy of the system increases. Like heat, the energy change from work always occurs as part of a process: a system can do work, but doesn't contain work.
