It’s easy to imagine that hot objects contain heat, but we can only understand how hot something is by how it affects other things. You know a fire is hot because it warms your cold house, and you realise your soup is hot when it burns your tongue. Generally speaking, temperature is a measurement that we use to describe the sensation of feeling warm or cold from an object. The molecules inside most things are constantly moving and when something gets hotter, the molecules move faster. So, the temperature of an object depends on the average energy of the movement of the molecules within it. We experience temperature every day. When it is hot outside we feel hot, when it is cold outside we teel cold. Temperature does not depend on the size or type of the object. It is a measure of the average energy of molecular motion in a substance.
