Question

How many Calories are required to melt a 1.52 g ice cube?

Answer 1

Hi, 

It would require 121.6 calories to melt a 1.52g ice cube.

$1.52 * 80= 121.6$

Answer 2

The latent heat of fusion of water at 0 °C is 79.7 calories/g.

This means 79.7 calories are required to melt 1 g of ice.

Thus, calories of heat required to melt 1.52 g of ice cube will be:

$1 g\rightarrow 79.7 calories$

Thus,

$1.52 g\rightarrow (1.52)(79.7)calories=121.15calories$

Thus, 121.15 calories are required to melt 1.52 g of ice cubes.
