Suppose you mix two identical blocks of metal, one having a temperature of 10 and the other 20 . Is it possible for the cold block to cool to 5 C and the warm block to warm to 25 C?

A. Yes, because it adheres to the second law of thermodynamics.
B. No, because it will violate the zeroth law of thermodynamics.
C. Yes, because it adheres to the zeroth law of thermodynamics.
D. No, because it will violate the first law of thermodynamics.

Temperature of identical objects is 10 C and 20 C , the equilibrium temperature would be:
10 C + 20 C 2 = 15 C
the first law of thermodynamics prohibits the flow of heat from a colder body to hotter body, thus the colder body cannot attain 5 C and warmer body cannot attain 25 C .Thus option D is correct.
