Question

$1gram$ of ice which on melting forms $1gram$ of water absorbs $80calories$ of energy.

• A. True
• B. False

Answer 1

The correct option is A True

The amount of heat required to convert one unit amount of the substance from solid phase to liquid phase at atmospheric pressure at its melting point is known as Latent heat of fusion. The latent heat of fusion is $80$ calories per gram.

So, to convert $1$gm of ice to $1$gm of water, ice needs to absorb $80$ calories of energy.
