“How do we quantify the energy released or absorbed during a constant temperature process?”
When we deal with energy and heat problems, we typically think of the system of having a change in temperature. However, when it comes to phase transitions it is possible to have a change in energy of a system without a corresponding change in temperature. So how have scientists and engineers decided to describe this phenomenon? Well, after much research into the subject, this process has been termed latent heat and is proportional to the energy required to change the phase of a substance divided by its mass, which can be symbolically described by the equation L=q/M.
