Question

The latent heat of fusion of ice is...... a) 540cal/g. b) 80 cal/g. c) 800 cal/g d) 4 cal/g ​

Answer 1

The latent heat of fusion of ice is 80 cal/g

• Option (b) is correct.
• Latent heat is the heat change related to the change of state (solid / liquid/gas).  
• This heat change is called the latent as it is not associated with a change in temperature.  
• The latent heat of fusion for ice is 80 calories per gram and this is the amount of heat is absorbed by each gram of ice in melting or is the amount of heat given up by each gram of water in freezing.
• Latent heat of fusion is the heat provided to a specific substance to change its state from solid to liquid.

Answer 2

Answer:

option B) 80 cal/g. is the correct option.
