Why is ice at 0°C more effective in cooling than water at 0°C?

First ice requires latent heat to convert into water at $0^°C$. 1 gram of ice at $0^°C$ needs 334 joules of heat to become water at $0^°C$.

  1. Ice- It absorbs $334 J/g$ to melt (latent heat). Then, it can absorb more heat as the water warms up.
  2. Water- It's already in liquid form. It cannot absorb latent heat (no phase change).

Therefore, Ice at $0^°C$ is more effective in cooling than water at $0^°C$ because it absorbs extra heat ($334 J/g$) during melting, without a rise in temperature.
