Question

1. A fixed temperature at which a solid changes
into liquid state is called
point.
2. The process due to which a gas changes
into liquid state at fixed temperature is
called
3. When a solid directly changes to gaseous
state on heating, without changing to the
liquid state, the gaseous material so formed
is called
4. The heat energy brings about a change in
the
of a material body.​

Answer 1

Answer:

1) The latent heat of fusion is the change heat required to change the state from a solid to a liquid or vice versa and this process is called fusion.

2) The process due to which a gas changes into a liquid at a fixed temperature is called vaporization.

3) The reverse of deposition is sublimation and hence sometimes deposition is called desublimation.

4) When heat energy is supplied to a body, there can be an increase in the dimension of the object. This change in the dimension due to rise in temperature is called thermal expansion of the object.
