Question

How much energy is required to melt a 250 gram ice cube?

Answer 1

Energy required to melt ice (Q) = 83500 j

Step-by-step explanation

Given

Mass of ice = 250 g

Required: Energy to melt ice

Solution

Ice melts at B, where the temperature is 0 °C.

To solve this question, we will use:

`Q\text{ = L}_(ice)\text{ x m}`

where Q is the amount of heat needed to melt the ice, L ice is the Latent Heat (or heat of fusion of water = 334 j/g) of melting for ice, and m is the given mass of ice.

Q = 334 j/g x 250 g

Q = 83500 j
