Heat TransferHard

Question

The specific heat of alcohol is about half that of water. Suppose you have identical masses of alcohol and water. The alcohol is initially at temperature TA. The water is initially at a different temperature TW. Now the two fluids are mixed in the same container and allowed to come into thermal equilibrium, with no loss of heat to the surroundings. The final temperature of the mixture will be :-

Options

A.Closer to TA than TW
B.Closer to TW than TA
C.Exactly halfway between TA and TW
D.Dependent on the volume of alcohol used

Solution

SW > SA so Teq will be closer to TW.
