Chapter 12, Problem 28PE

Interpretation Introduction

Interpretation:

Final volume of swim bladder in sward fish if temperature is changed from $28°\text{C}$ to $12°\text{C}$ and pressure is changed from $755\text{ torr}$ to $2577\text{ torr}$ has to be determined.

Concept Introduction:

Combination of three laws Charles' law, Boyle's law, and Gay-Lussac's law form combine law. This law used to determine change in pressure, volume and temperature if two of them got varied.

Mathematically relation for combined law is as follows:

  $\frac{PV}{T}=k$

Or,

  $\frac{P_1{V}_1}{T_1}=\frac{P_2{V}_2}{T_2}$

Here,

$P_1$ is initial pressure.

$P_2$ is final pressure.

$T_1$ is initial temperature.

$T_2$ is final temperature.

$V_1$ is initial volume.

$V_2$ is final volume.
