WebJan 22, 2024 · When condensing, the vapor will gradually phase change to liquid until all that remains is 100% liquid. This phase change, or change of state, is an example of a latent heat rejection process. This is because the heat that is being removed while phase changing is latent heat, not sensible heat. omniphics sdn bhd
