Is the following correct?
Temperature is the measure of how hot or cold something is; not how much thermal energy it has.
Examples; 1 kg of boiling water has a temperature of 100 degrees C and has heat energy of 4.184 kJ (the specific heat capacity of water).
1 kg of lead heated to a temperature of 100 degrees C has the same temperature as the kg of boiling water but only has 128 J of thermal energy.
But temperature is also a measure of how much kinetic energy the particles of a substance has (or is this just another way of saying how hot or cold it is?).
