Something which allows heat to flow through it easily.
high melting point
Something with a high melting point has to be at a very high temperature before it melts. It is a solid at room temperature.
low boiling point
Something with a low boiling point will turn into a gas at a relatively low temperature. It can be a solid, liquid or gas at room temperature.
