PPT-14   Heat, Specific heat, and Latent heat

Heat Heat is energy that flows from a highertemperature object to a lowertemperature object because of the difference in temperatures SI Unit of Heat joule J SI unit for heat is the joule J. – A2 Physics LOJ 2010 cyberphysics.co.uk 1 1. An electrical heater is used to heat a 1.0 kg block of metal, which is well lagged. The table shows how the C. ontents:. Phases of matter. Changing phase. Latent heat. Graphs of phase change.

On the front counter there is a perpetually thirsty bird. Do NOT touch him.. Write down all your . observations. of the motion. Do not try to explain why it’s happening—just look at WHAT is happening. . These areas have extra notes to help you.. Make notes as we go along, always including these post-its. Notes. Objectives. Objectives. BRONZE. To define ‘latent heat’. SILVER. To be able to measure latent heat. Introduction to Heat. Heat is a form of energy.. A large amount of energy ends up as heat.. Example: in a car some of the chemical energy stored in petrol is turned into heat energy. . 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. Define the term ‘internal energy’.. Explain the differences in the forces of attraction found between particles of a gas compared to particles of a solid.. Explain what is meant by ‘latent heat’. Qnet. = (. Downwelling.
