In an ideal gas at temperature $T$ , the average force that a molecule applies on the walls of a closed container depends on $T$ as $T^{q}$ . A good estimate for $q$ is

Answer:

1.00

Solution:

The pressure exerted by molecules of a gas on the walls $p = \frac{1}{3} n m c^{2}$

$∴ p \propto c^{2}$

But $C \propto \sqrt{T}$ and $C^{2} \propto T$

$∴ P \propto T$

$∵$ Force $= P \times A$

$∴ F \propto T^{1}$

$q = 1$
