 Hi Harsimran!

In a quantum level, the considered particle can only take on certain distinct values of energy, called energy levels.

The sensation of heat and cold is always a comparative consequence. It is due to the difference between the human body and their surroundings that they either feel hot or cold.If the ambient temperature is more we feel hot and if it is less we feel cold.In addition to this, we have temperature sensors in our nervous system

Whereas the amount of heat in terms of magnitude is totally different than the sensation of heat. At quantum level heat is given two distinct attributes as hot and cold so that there is clarity in determining the extent of the heat energy.

Hope this helped :)
