Question

16. If a gas expands at constant temperature, it indicates
that
[AIPMT (Prelims)-2008]
(1) Number of the molecules of gas increases
(2) Kinetic energy of molecules decreases
(3) Pressure of the gas increases
(4) Kinetic energy of molecules remains the same​

Answer 1

Answer:

4

Explanation:

K.E of molecules remains constant

Answer 2

Ello.. ✌✌

If a gas expands at constant temperature it indicates that Kinetic energy of molecules remains the same since the pressure of the gas decreases and the number of molecules of gas remains constant.

Option d) is the correct answer.
