Which of the following statements is true based on the kinetic-molecular theory of matter? when the volume of a gas decreases, the pressure increases. when the pressure of a gas decreases, the temperature increases. when the volume of a gas increases, the temperature decreases. when the pressure of a gas increases, the volume increase

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

Explanation:

Main point of kinetic matter theory:

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.

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
