Chapter 1, Problem 1A.7P

(a)

Interpretation Introduction

Interpretation: The change in pressure on changing temperature by $1\text{K}$ from the pressure of $6.69\text{kPa}$ and temperature of $273.16\text{K}$ has to be calculated.

Concept introduction: The perfect gas equation is given for the gases which follow a specific rule under certain conditions.  This is represented by the formula given below as,

  $pV=nRT$

Where,

• Ø  $p$ is the total pressure.
• Ø  $V$ is the volume.
• Ø  $n$ is the number of moles.
• Ø  $R$ is the gas constant.
• Ø  $T$ is the temperature.

(b)
