Why is ice at 273 k more effective in cooling than water at the same temperature ?? Class 9 in HINDI

In this Science video for class 9 in Hindi we explained why ice at 273 k is more effective in cooling than water at the same temperature. This is a topic of chapter 1 - 'Matter in our Surroundings' of class 9th science from NCERT.

As we know 273 k is the same as 0 degree Celsius. Water exist is two states, solid and liquid, at 0 degree Celsius. But 273 k water has more heat energy than 273 k ice. Hence, ice at 273 k more effective in cooling than water at the same temperature.

The heat required for ice to convert into water is 3,34,000 joule/kg. This heat energy is known as the latent heat of fusion for water.
