Question

The diffusion coefficient of an ideal gas is directly proportional to its mean speed and to its mean free path. The absolute temp of an ideal gas is increased 9 times and its pressure is increased 3 times, due to which diffusion coefficient increases x times. The value of 'x' is
ANSWER FAST PLEASE

Answer 1

Answer:

The diffusion coefficient of an ideal gas is proportional to its mean free path and mean speed. The absolute temperature of an ideal gas is increased 4 times and its pressure is increased 2 times. As a result, the diffusion coefficient of this gas increases x times.
