The concentration of gas molecules was increased by 4 times and the average kinetic energy did not change. how the gas pressure will change.
Gas pressure can be represented by the formula:
Р = 2/3 * n * E, where n is the concentration of gas molecules, E is the average energy of translational motion of gas molecules, average kinetic energy.
Initial gas state:
Р1 = 2/3 * n1 * E, according to the condition of the problem E – const.
Final gas state:
P2 = 2/3 * n2 * E, by the condition of the problem n2 = 4n1.
P2 = 2/3 * 4n1 * E = 4 * 2/3 * n1 * E = 4P1.
Answer: The pressure of the given gas will increase by 4 times.
