[Maximum number: 2]

A sample of $0.26 \mathrm{~m}^{3}$ of an ideal gas is at pressure $2.0 \times 10^{5} \mathrm{~Pa}$ and temperature 290 K .

Determine:

the average translational kinetic energy $E_{\mathrm{K}}$ of one molecule of the gas

E_{\mathrm{K}}=\ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots \ldots . . \mathrm{J}[2]

$E_{\mathrm{K}}=(3 / 2) k T$ $\begin{aligned} E_{K} =(3 / 2) \times 1.38 \times 10^{-23} \times 290 =6.0 \times 10^{-21} \mathrm{~J} \end{aligned}$
