different properties of solids, liquids and gases
solid
the particles are arranged in a lattice so they can't move and that is why solids are better at conduction
liquid
the particles are still touching each other but they can move around and that is why convection is possible

convection
convection current
Convection is heat transfer due to a density differential within a fluid. As water's temperature increases in the presence of a heat source, it will become less dense and rise. As it moves up and away from the heat source, it cools and becomes more dense and sinks
-
Radiation
Objects lose thermal energy by emitting infra-red and objects gain thermal energy by absorbing infra-red

expansion
when a material is heated the kinetic energy of that material increases and the atoms move about more therefore there has to be more space so the material expands which means that the atoms are free to move in a bigger space
