A thin copper wire at $$300^\circ$$ is suddenly immersed in water at $$30^\circ C$$. It cools down to $$150^\circ C$$ in 70 seconds. It is then reheated to the initial temperature of $$300^\circ C$$ and suddenly exposedto air at $$30^\circ C$$ whereit cools down to $$150^\circ C$$ in 200 seconds. This difference in cooling time is due to

A

Larger specific heat of water

B

Larger heat transfer coefficient in water

C

Smaller heat transfer coefficient in water

D

None of the above
