Question

The kinetic energy of a mole of ideal gas in calories is approximately equal to
(A) 3 times its absolute temperature
(B) 2 times its absolute temperature
"C) 4 times its absolute temperature
D) 2/3 times its absolute temperature​

Answer 1

Answer:

D.2/3 TIMES ITS ABSOLUTE TEMPERATURE......

Answer 2

The “kinetic energy of a mole” of the ideal gas in the calories is approximately “equal to three times” its absolute temperature.

Answer - (Option A)

Explanation:

This is because the absolute temperature is directly proportional to the ‘average kinetic energy’ per gas molecule and is equal to

K.E. av = $\frac{3}{2} K T.$

                             $K . E=\frac{3}{2} n R T=3 T$

Any change in “pressure or volume” of the gas will change the absolute  temperature.

And the answer is "3 times its absolute temperature".
