Question

the mean kinetic energy of gas at 300 k is 100j the mean energy of the gas at 450 k is equal to
100J
300J
450J
150J​

Answer 1

Answer:

the mean energy of gas at 450 k is 150J.

Explanation:

mean K.E of gas =3/2 K×T

(where K- Boltzmann

constant

T- temperature)

therefore,

K.E proportional to Temperature

So, 100/x =300/450

x= 150 J
