Question

name the temperature at which (a)a liquid changes into a gas (b) a solid change to liquid

Answer 1

a) a liquid changes into a gas by 100° boiling

Answer 2

Name the temperature at which :

　

1. Liquid changes into a gas.
2. A solid change to liquid.

　

This concept is of “Temperature changes effect the States of Matter” :

　

(1)............

• The temperature at which liquid change into a gas is about 100°Celcius.

　

• This is the latent head of vaporisation of water into water vapour.

　

• The particles of water move into stem at 373 Kevin that's about (100°Celcius).

　

(2)...........

• To change solid ice into a liquid, it can also be heated and needs to have a high temperature about above 50°C to 100°C.

Extra point:

• SI unit of temperature is Kevin.
