What change or changes in the state of a gas bring about each of the following effects?

(a) The number of impacts per unit time on a given container wall increases.

(b) The average energy of impact of molecules with the wall of the container decreases.

(c) The average distance between gas molecules increases.

(d) The average speed of molecules in the gas mixture is increased.

Expert Solution

a) Increase in pressure of gas results in increase in the number of impacts per unit time as given container wall.

b) Average energy is directly proportional to temperature.

Decrease in temperature of gas sample results in decrease in average energy of impact of molecules with the wall of container.

c) When the volume of gas increases and pressure decreases, the average distance between gas molecules increases.

d) Increase in temperature

v̅ = √3RT/M

Speed ∝ √T

a) Increase in pressure of gas results in increase in the number of impacts per unit time as given container wall.
