Question

at a constant pressure average kinetic energy of the gas molecules increase 2 times if

Answer 1

Answer:

temperature is increased by 2 times

Explanation:

Answer 2

THE KINETIC ENERGY OF A GAS MOLECULE INCREASES BY 2 TIMES “WHEN TEMPERATURE IS INCREASED BY 2 TIMES”.

Explanation:

• The kinetic energy of a molecule is due to its motion.
• When temperature increases the molecule attains energy and moves with a faster velocity.
• The formula of kinetic energy is: $K.E=3/2kT$.
• According to this equation the kinetic energy is directly proportional to temperature, so if the temperature is doubled, the K.E will also become two times.
• Therefore, if temperature is increased by 2 times, the K.E increases by 2 times.

[Your question is incomplete, but most probably your full question was - At constant pressure average kinetic energy of gas molecules increases 2 times if

a. temperature is increased by 2 times

b. temperature is halved

c. no change in temperature

d. none of above  ]
