Solution

The correct option is B False
Heat is absorbed by ice when it changes into water.
Melting or Fusion: The process due to which a solid change into a liquid state by absorbing heat energy is called melting or fusion.
The kinetic energy (K.E.) of solid particles increases by increasing the temperature.
The particles start vibrating with greater speed, due to an increase in kinetic energy.
The energy supplied by heat overcomes the force of attraction between the particles. Then, the particles leave their fixed positions and start to move freely, and thus solid changes into a liquid.

Q. How much heat energy is released when

5.0 g

water at

42^{\circ} C

changes into ice at

0^{\circ} C

? Take specific heat capacity of water =

336 J g^{- 1}

Calculate the amount of heat released when $5.0 g$ of water at $20 {}^{\circ}C$ is changed into ice at $0 {}^{\circ}C$ .
(Specific heat capacity of water $= 4.2 J / g {}^{\circ}C$ ,
Specific latent heat of fusion of ice $= 336 J / g$ )

Q. 28.How much heat energy is released when 5.0 g of water at 20 degree celsius changes into ice at 20 degree celsius? Take specific heat capacity of water= 4.2 J per g per K, specific latent heat of fusion of ice=336 J per g.

Calculate the amount of heat released when 5.0 g of water at 20 °C is changed into ice at 0 °C.

Specific heat capacity of water = 4.2J g^-1 °C^-1, Specific latent heat of fusion of ice = 336 J g^-1.

When ice changes into water, there is no change in:
