Question

How much heat must be transferred for 10 g of liquid water at 0°C to become ice? Is it absorbed or released?

80 calories released

80 calories absorbed

800 calories absorbed

800 calories released

Answer 1

Option (d) is correct. 800 calories of heat is released.

Step-by-step explanation:

The formula for the heat is given by

Q= m L

Q= heat energy

m= mass =10 g

L= latent heat of fusion=80 cal/gram

so Heat energy= Q= 10 (80)=800 cal

the heat energy is released.

so 800 calories of heat is released.
