Question

amount of ice will remain 52 g ice is added to 100 g of water at 40℃​

Answer 1

The question is partly incomplete and here is the complete question,

What amount of ice will remain when 52g of ice at 0°C is added to 100g f water at 40°C. specific heat of water is 1 cal/g and latent heat of fusion of ice is 80 cal/g?

26g of ice remains as ice.

Explanation:

Here we have 52 g ice at 0°C, and 100 g of water at 40°C.

Water comes to 0°C by loosing a heat of $ms(40-t)=52*1*(40-0)= 2080 cal$

• ice gaines 2080 cal and change state to water.

2080 calories will melt, $2080= mL=m*80$

⇒m=26 g

therefore, 26 g of ice melts and remaining 26 grams remains as ice.
