Chapter 10, Problem 19RQ

Interpretation Introduction

Interpretation:

The process of collection of gas over water and the importance of knowledge of temperature of that gas while estimating its pressure is to be explained.

Concept Introduction:

Pressure is the applied force per unit area. The mathematical expression for pressure is:

$P=\frac{F}{A}$

Here $P$ is pressure, $F$ is force applied and $A$ is the area. The SI unit of pressure is ${\text{N/m}}^2$(newton per meter square) or $\text{Pa}$(pascal).
