Symbol cp (for constant pressure) Also called specific heatQ=mc(delta)T specific latent heats of fusion The amount of heat released / absorbed from a substance at constant temperature as you change state from liquid->solid / solid->liquid.Read more: vaporization the transition of matter from a solid or liquid phase into a gaseous (or vapor) phase. Water boiling into steam is an example of vaporization why does temperature stay constant during a phase change Because the energy is all being used to change the state of the substance (ordering the molcules) instead of increasing the temperature ("jiggling" the molecules.(isothermal change) AuthorAnonymous ID121860 Card Setphysics 3.1 Descriptionirmo high school Updated2011-12-08T16:16:09Z Show Answers
