HEAT

Heat that is absorbed during melting and boiling without change in temperature is known as

• Heat capacity

• Specific heat capacity

• Latent heat

• Specific Latent Heat

Latent heat is released during

• Freezing

• Boiling

Latent heat is absorbed during

• Melting

• Condensation

During the changes in the phase of matter such as melting and boiling, the temperature

• increases

• remains constant

• decreases

Melting point is when

• solid is changing to liquid

• liquid is changing to solid

When ice melts, the ice molecules _____________ causing ice to change from solid to liquid.

• release latent heat of fusion

• absorb latent heat of fusion

• release latent heat of vaporisation

• absorb latent heat of vaporisation

When water boils, the water molecules __________________ causing water to change from liquid to gas.

• absorb latent heat of vaporisation

• release latent heat of vaporisation

• absorb latent heat of fusion

• release latent heat of fusion

When water vapour condenses, the water vapour molecules __________________ causing water vapour to change from gas to liquid.

• absorb latent heat of vaporisation

• absorb latent heat of fusion

• release latent heat of vaporisation

• release latent heat of fusion
