Question

5 liters of water at $0^{\circ }C$ is mixed with 1 liter of water at ${50}^{\circ }C$. The resulting temperature will be

• A. $<0^{\circ }C$
• B. $>{50}^{\circ }C$
• C. $Between{0}^{\circ }Cand{50}^{\circ }C$
• D. Insufficient information

Answer 1

The correct option is C $Between{0}^{\circ }Cand{50}^{\circ }C$

When 5 liters of water at $0^{\circ }C$ is mixed with 1 liter of water at ${50}^{\circ }C$, water at ${50}^{\circ }C$ will lose heat to water at $0^{\circ }C$. This will continue till thermal equilibrium is reached. This equilibrium temperature will lie between $0^{\circ }C$ and ${50}^{\circ }C$.
