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

Correct answer

1

Step-by-step solution

The pressure exerted by molecules of a gas on the walls p=13nmc2p = \dfrac{1}{3}nm{c}^{2}

∴p∝c2∴ p ∝ {c}^{2}

But C∝TC ∝ \sqrt{T} and C2∝T{C}^{2} ∝ T

∴P∝T∴ P ∝ T

∵∵ Force =P×A= P \times A

∴F∝T1∴ F ∝ {T}^{1}

q=1q = 1
