![### Heat Transfer and Entropy Change in Water Mixture
#### Problem Statement:
1. (a) In reaching equilibrium, how much heat transfer occurs from 1.4 kg of water at 40°C when it is placed in contact with 1.4 kg of 20°C water? The specific heat of water \( c = 4186 \) J/(kg°C).
**Hint:** If the masses of water are equal, what is the equilibrium temperature of the water mixture?
\[
Q = \boxed{\phantom{0000}} \text{ J}
\]
(b) What is the change in entropy due to this heat transfer?
\[
\Delta S_{\text{total}} = \boxed{\phantom{0000}} \text{ J/K}
\]
(c) How much work is made unavailable, taking the lowest temperature to be 20°C?
\[
W_{\text{unavailable}} = \boxed{\phantom{0000}} \text{ J}
