What's on this checklist

Core

I can describe, qualitatively, the thermal expansion of solids, liquids and gases at constant pressure.
I can describe some everyday applications and consequences of thermal expansion.
I know that raising the temperature of an object increases its internal energy.
I can describe melting and boiling in terms of an energy input with no change in temperature.
I know the melting temperature and the boiling temperature of water at standard atmospheric pressure.
I can describe condensation and solidification in terms of particles.
I can describe evaporation in terms of more-energetic particles escaping from the surface of a liquid.
I know that evaporation cools a liquid.

I can explain, in terms of the motion and arrangement of particles, the relative order of magnitude of the expansion of solids, liquids and gases as their temperature rises.
I can describe a rise in the temperature of an object in terms of a rise in the average kinetic energies of all the particles in the object.
I can define specific heat capacity as the energy needed per unit mass per unit temperature increase, and I can recall and use the equation c = ΔE/(mΔθ).
I can describe experiments to measure the specific heat capacity of a solid and of a liquid.
I can describe the differences between boiling and evaporation.
I can describe how temperature, surface area and air movement over a surface affect evaporation.
I can explain why an object in contact with an evaporating liquid cools down.
