Describe the movement of the particles of helium gas inside the balloon.
range of speeds.moving in different directions accept random motion
1 of 5
What name is given to the total kinetic energy and potential energy of all the particles of helium gas in the balloon?
internal energy
2 of 5
Describe the difference between the solid and gas states, in terms of the arrangement and movement of their particles.
SOLID particles vibrate about fixed positions. closely packed accept regular.GAS particles move randomly accept particles move faster accept freely for randomly.far apart
3 of 5
What is meant by ‘specific latent heat of vaporisation’?
amount of energy required to change the state of a substance from liquid to gas (vapour) .Unit mass / 1 kg dependent on first marking point 1
4 of 5
The temperature of the liquid in the container decreases as the liquid evaporates. Use kinetic theory to explain why.
escapingparticles are getting further apart is insufficient 1 (ii) accept molecules / atoms for particles
