The first law of thermodynamics states that: a) heat can by itself pass from a lower temperature to a higher temperature. b) heat can't by itself pass from a lower temperature to a higher temperature.

(b) Heat can not itself pass from lower temperature to a higher temperature.

Explanation:

Thermodynamics is the process of relating heat with the other energies.

First law of thermodynamics say that about the conservation of energy the creation of energy is not possible nor the destruction is possible, we can only transfer from one form of energy to the other form.

This law suggest that heat cannot transfer from lower temperature to higher temperature without doing any external work or without changing its internal energy.
