PPT-Latent Heat

These areas have extra notes to help you Make notes as we go along always including these postits Notes Objectives Objectives BRONZE To define latent heat SILVER To be able to measure latent heat. The latent heat process happens at a low and the low pressure in this LATENT HEAT - CONDENSER more of the gas condenses into a liquid until you achieve a solid column of liquid at the outlet of the co – A2 Physics LOJ 2010 cyberphysics.co.uk 1 1.

Heat can have a significant effect on solids, liquids and gases (such as expansion).. Section 9.1: Temperature and Thermal Equilibrium. Defining Temperature. Temperature: a measure of the average kinetic energy of the particles in a substance. Adding or removing energy usually changes temperature. Heat. Heat. is energy that flows from a higher-temperature object to a lower-temperature object because of the difference in temperatures.. SI Unit of Heat:. joule (J).. SI unit for heat is the joule, J.
