Chapter 7, Problem 7.61P

Interpretation Introduction

Interpretation:

The pressure inside the autoclave is to be determined when the autoclave containing the steam at temperature $100°\text{C}$ and 1.0 atm pressure which then heated to $150°\text{C}$.

Concept introduction:

According to Gay Lussac's law, the pressure of gas is directly proportional to the temperature of the gas in K at constant volume. This relation is represented as −

  $P\propto T$

Or,

  $P_2=\frac{P_1{T}_2}{T_1}$

  $T_2=\frac{P_2{T}_1}{P_1}$

Here,

P₁= initial pressure

P₂ = final pressure

T₁ = initial temperature

T₂ = final temperature
