P1 - Moving and Storing Heat 3.0 / 5 based on 1 rating ? PhysicsEnergyGCSEOCR Created by: RebeccaCreated on: 04-12-12 18:38 When a substance is heated, what happens to the particles? They gain kinetic energy. 1 of 10 What does this energy do to the particles in a gas or liquid? Make them move faster. 2 of 10 What does this energy do to the particles in a solid? Make them vibrate more rapidly. 3 of 10 What does it mean if this energy is measured on an absolute scale? It can't go below 0 4 of 10 What is temperature a measure of? The average kinetic energy of particles in a substance. 5 of 10 When will energy flow between two objects? If there is a difference in temperature between them. 6 of 10 What does energy tend to flow between? From hot objects to cool. 7 of 10 The greater the difference in temperature, the.... faster the rate of cooling will be. 8 of 10 What is specific heat capacity? The amount of energy a substance can store. 9 of 10 Why is water good for central heating systems? Because it has a high specific heat capacity, so can store lots of energy. 10 of 10
