... Boyle’s Law: pV = constant - Temperature remains constant (isothermal) - pV = constant and p1V1 = p2V2 - ΔU = 0 because the internal energy is dependent on temperature, which does not change - ΔQ = ΔW. If the gas expands to do work ΔW, & amount of heat ΔQ must be supplied - compression or expansion ...
