11. Name two gases that are supplied in compressed state in homes and

12 Is evaporation an exothermic or endothermic process? Explain.
13.When we supply heat energy to water , particles start moving even faster . At a certain temperature , a point
is reached when the particles have enough energy to break free from the forces of attraction of each other . At this
temperature the liquid starts changing into gas . The temperature at which a liquid starts boiling at the
atmospheric pressure is known as its boiling point . Boiling is a bulk phenomenon . Particles from the bulk of the
liquid gain enough energy to change to its vapour state .
Based on your understanding of the above passage , tick the correct option in the following questions .
The boiling point of a liquid is :
a) directly proportional to atmospheric pressure
b) inversely proportional to atmospheric pressure
c) independent of atmospheric pressure
14. At its boiling point:
a)
b)
c)
d)
the temperature of the vapour is more than that of the boiling liquid
the temperature of the vapour and the boiling liquid is the same
the vapor is hotter than the boiling liquid
the vapor and the boiling liquid have the same amount of heat
