Question 246: Thermodynamics & KTG

Question

The root mean square velocity of molecules of gas is

Accepted Answer

The rms speed of a gas molecule is
$
\mathrm{V}_{\mathrm{RMS}}=\sqrt{\frac{3 \mathrm{RT}}{\mathrm{M}}}
$
$\mathrm{V}_{\mathrm{RMS}}  \propto \sqrt{\mathrm{T}}$

Answer

Proportional to temperature ($T$)

Answer

Inversely proportional to square root of temperature $\left( {\sqrt {{1 \over T}} } \right)$

Answer

Proportional to square of temperature ($T^2$)

Answer

Proportional to square root of temperature ($\sqrt T$)
