Why does atmospheric temperature fall after hail storm?

टीपा लिहा

उत्तर

Ice has the highest sp. latent heat of fusion of 336,000 Jkg-1. Thus, when hails melt, they absorb large amount of heat energy from surroundings. Thus, atmospheric temperature drops.

1 kg of ice at 0°C is heated at a constant rate and its temperature is recorded after every 30 s till steam is formed at 100℃. Draw a temperature time graph to represent the change of phase.


The amount of heat energy required to convert 1 kg of ice at – 10℃ to water at 100℃ is 7,77,000 J. Calculate the specific latent heat of ice. Specific heat capacity of ice = 2100 J kg-1K-1, Specific heat capacity of water = 4200 J kg-1 K-1.
