Fill in the chart below to identify the name of the process that explains the state of change indicated, the states of matter being changed, or the points at which the process occurs.

1.  Changing from solid to a liquid is called melting / fusion and happen

at the melting/ fusion point.

Reason: melting point is a temperature at which a solid melt and converts into liquid by providing heat.

2. Changing from liquid to gas is called evaporation/boiling and happens at the evaporation/boiling point.

Reason. Evaporation is a process in which molecules from surface of liquid convert into gas.

3.   Changing from a gas to a liquid  is called condensation and happens at the condensation point.

Reason : In condensation process  gas particles converts into liquid droplets.

4. Changing from liquid to a solid is called freezing and happens at the freezing point.

Reason : Freezing is a process that convert liquid into soilid state by decreasing temperature of that specific liquid,

ice to water 1 water to vapour 2 latent heat
