Why is ice at 273k more effective in cooling than water at the same temperature?

Explanation

### Step-by-Step Solution:

1. **Understanding the State of Matter**: Ice and water are two different states of the same substance (H2O). At 273 K, both exist at the freezing/melting point of water.

2. **Latent Heat Absorption**: When ice is at 273 K and is introduced to a warmer environment, it absorbs heat in two ways:
- It absorbs **latent heat** (the heat required to change its state from solid to liquid without changing its temperature).
- It also absorbs **thermal energy** (the heat that raises the temperature of the substance).
