How much heat energy, in kilojoules, is required to convert 80.0 g of ice at −18.0 ∘C to water at 25.0 ∘C ?
Expert Answer
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.
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
Step 2: Melt ice at zero degree celcius
Heat absorbed to melt ice to water is called as heat of fusio...
