Calculate the amount of heat necessary to convert 34g of ice at -3’C into liquid water at 25’C

Question

I cant understand the notes to answer this...I need this for a blueprint to answer other questions for HW

Answer 1

Actually

Answer 2

You need to calculate three separate heats.

1. Warm the ice from -3 C to 0 C

Heat = mass x T change x specific heat of ice

2. Melt the ice at 0 C

Heat = mass x Heat of fusion

3. Warm the water from 0 C to 25 C

Heat = mass x T change x specific heat of water

Add the three heats together to get the total heat required.
