Assertion (A) :
If a hot metal ball is quenched in a liquid of low temperature, heat transfer will take place from metal ball to liquid and not in the reverse direction.
Reason (R) :
Heat transfer process from hot metal ball to liquid at lower temperature complies with the increase of entropy principle i.e. S${}_{\mathrm{gen}}$ ≥ 0 and the reverse process does not.
