  • A t-shirt
Q.2
Which of the following best explains evaporation?
  • Rapid moving/vibrating atoms interact with neighbour atoms transferring kinetic energy
  • High energy particles break free of the liquid at the surface
  • The particles heat independently of one another
  • High energy particles break free from the liquid throughout the whole container
Q.3
What is condensation?
  • The transfer of energy between two particles in a solid structure
  • Vaporisation of a liquid occurring on the surface of the liquid
  • A change in state of matter from a gas to a liquid
  • It is a small town outside Manchester
Q.4
What does the rate at which an object transfers energy by heat depend on?
  • Surface area and volume
  • Material of the object
  • The nature of the surface with which the object is in contact

Q.5
How does convection occur?
  • By condensing a gas
