Answer:

The correct statement is :When the volume of a gas decreases, the pressure increases.

Step-by-step explanation:

Main point of kinetic matter theory:

  • Matter is made of constantly moving small particles.
  • All matter posses some energy which also depends upon the temperature of the matter.Solid possess least amount of energy where as gases posses grater amount of energy.
  • Change in state of matter occur when change in energy takes place.
  • There are space between the particles of matter.As matter transits from solid to gas these space between particles increases.
  • Attractive force between the particles increases when particle moves closer to each other.

When we increase the pressure of the on the particles of matter the space between them will get decrease due to which attractive force between the particles will also get increase by which they will come closer and result in decrease in volume of the matter.
