A sample of gas is enclosed in a container of fixed volume. Identify which of the following statements are true. Check all that apply.If the container is heated, the gas particles will lose kinetic energy and temperature will increase.
If the container is heated, the gas particles will lose kinetic energy and temperature will increase.
If the container is cooled, the gas particles will lose kinetic energy and temperature will decrease.
If the gas particles move more quickly, they will collide more frequently with the walls of the container and pressure will increase.
If the gas particles move more quickly, they will lose energy more rapidly and collide with the walls of the container less often, and pressure will decrease.
If the gas particles move more quickly, they will collide with the walls of the container more often and with more force, and pressure will increase.

The answers are,

B. If the container is cooled, the gas particles will lose kinetic energy and temperature will decrease.

C. If the gas particles move more quickly, they will collide more frequently with the walls of the container and pressure will increase.

E. If the gas particles move more quickly, they will collide with the walls of the container more often and with more force, and pressure will increase.

Explanation:

As kinetic energy is the energy obtained by an object due to its motion. And, relation between kinetic energy and temperature is as follows.

                   K.E = [tex]\frac{3}{2}kT[/tex]

Hence, more is the increase in temperature more will be the kinetic energy of molecules of a substance.

Therefore, with increase in kinetic energy there will occur more number of collisions as molecules collide with a force on the walls of a container which will lead to an increase in pressure also.

And, on losing kinetic energy the molecules of the substance will come closer to each other. Therefore, a decrease in temperature of the substance will also occur.

Therefore, we can conclude that the true statements are as follows.

  • If the container is cooled, the gas particles will lose kinetic energy and temperature will decrease.
  • If the gas particles move more quickly, they will collide more frequently with the walls of the container and pressure will increase.
  • If the gas particles move more quickly, they will collide with the walls of the container more often and with more force, and pressure will increase.
