Chapter 15, Problem 15.21P

Interpretation Introduction

Interpretation:

Whether any liquid exists at temperature $60\text{°C}$ or not has to be determined.

Concept Introduction:

Gaseous molecules have least or no intermolecular attraction between them so they are free to move everywhere. Therefore they are referred to as ideal gas and obey ideal gas equation which is as follows:

  $PV=nRT$

Here,

$P$ is pressure in atmospheric pressure.

$V$ is volume in liter.

$n$ is moles of substance.

$R$ is the gas constant.

$T$ is the temperature in kelvin.

But in real, gases are non ideal means there are some amount of intermolecular forces in them which is the reason behind them being liquefied.
