Expert Answer

Step 1

Heat (q) is absorbed to convert ice to water.

Here, we have to calculate the total heat consumed in the process of converting ice to water.

 

Step 2

First heat ice to make water. This is a two step process.

mass of ice (m) = 80 g

Calculation in the picture

Heat absorbed to heat ice = 3038.4 J
