Core science paper 1 physics 0.0 / 5 ? PhysicsEverything in P1GCSEAQA Created by: homer00Created on: 10-05-16 08:48 How can heat energy be transferred? Conduction, convection and radiation 1 of 13 How can heat radiation be transferred? Infrared radiation 2 of 13 What is conduction? Conduction of heat energy is the process where vibrating particles pass on their extra kinetic energy to neighbouring particles. 3 of 13 What is convection? Convection occurs when the more energetic particles move from the hotter region to the cooler region and take their heat energy with them. 4 of 13 What is evaporation? Evaporation is when particles escape from a liquid at temperatures lower than boiling point. 5 of 13 * What is the equation for payback time Initial cost Annual saving 6 of 13 What are the 9 types of energy? Kinetic, heat, light, Gravity, chemical, sound, electrical& elastic. 7 of 13 What is the conservation of energy principle? Energy can be transferred, usefully from one form to another, stored or dissipatated but can never be created or destroyed. 8 of 13 * What is the formula for efficiency? Efficiency Power X time 9 of 13 What is a snakes diagram? Shows how much of the total energy is useful and how much is wasted 10 of 13 * What is e equation for energy? Energy Power X time 11 of 13 * What is the formula for the number of units used? No of units= power X time 12 of 13 * What is the formula for cost No of units X price of units 13 of 13
