Physics: Energy Revision 0.0 / 5 ? PhysicsEnergyGCSENone Created by: nelliottCreated on: 09-05-21 11:44 What is the equation for specific heat capacity? Change in energy = mass x SHC x temperature change 1 of 17 What i the equation for specific latent heat? Energy = mass x SLH 2 of 17 What do you use to measure the volume of a cuboid? You use a ruler. The equation is volume = width x height x depth 3 of 17 What is internal energy? The total kinetic energy and potential energy 4 of 17 What is latent heat of vaporisation Energy for a state change between liquids and gas 5 of 17 What is specific heat capacity? The energy needed to raise the temperature of a 1kg of a substance by 1 degree Celsius 6 of 17 What is the equation for denisty? Density = mass / volume 7 of 17 What is latent heat? The energy needed for a 1kg of a substance to change state (with no change in temperature) 8 of 17 In a heating graph what areas of the graph show a directly proportional relationship? The regions in which the particles are changing temperature, not state 9 of 17 In a heating graph what regions have a gradient of zero? The regions in which the substance is changing state, not changing temperature 10 of 17 What do you use to measure the volume of an irregular object? A displacement can measuring cylinder to measure the volume of water displaced 11 of 17 What are the units for specific latent heat? J/kg 12 of 17 Why is the mass conserved during state changes? The total number of particles does not change 13 of 17 What affects the temperature change when a substance is heated? The mass of the substance, the material being heated, the energy input 14 of 17 The volume of liquid displaced by a sinking object is... Equal to the volume of the object 15 of 17 `Why is energy needed for changes of state? To overcome the forces of attraction between the particles 16 of 17 What is the latent heat of fusion? The energy for a state change between solid and liquid 17 of 17
