Chapter 3, Problem 3B.7BST

Interpretation Introduction

Interpretation:

Volume of $2\text{g}$ of $\text{He}$ at $25\text{°C}$ and $1\text{atm}$ has to determined.

Concept Introduction:

An ideal gas contains a large number of randomly moving particles that are supposed to have perfectly elastic collisions among themselves. It is a theoretical concept. Gases that show perfect elastic collision are practically not possible. At higher $T$ and lower $P$ gases behave almost ideally.

Ideal gas law is an equation of state for any hypothetical gas. Expression for ideal gas equation is as follows:

  $PV=nRT$

Here,

$P$ is pressure of the gas.

$V$ is volume of gas.

$n$ denotes number of moles of gas.

$R$ is gas constant.

$T$ is temperature of gas.
