RAMADHAN DAY 1 QUESTION
During iftar, a student prepares a cold drink by adding ice into warm water.
A cup contains 200 g of water at 60 Ā°C.
The student adds 50 g of ice at 0 Ā°C.
Given:
- Specific heat capacity of water, c = 4200 J kgā»Ā¹ Ā°Cā»Ā¹
- Specific latent heat of fusion of ice, L = 3.34 Ć 10āµ J kgā»Ā¹
1. Calculate the heat lost by the warm water if the final temperature becomes 20 Ā°C.
2. Calculate the heat required to completely melt the ice.
3. Determine whether all the ice melts. Show your reasoning.
