Question

$88$ $c{m}^3$ of nitrogen is at a pressure of 770 mm mercury. If the pressure is raised to 880 mm Hg, find by how much the volume will diminish, temperature remains constant.

Answer 1

V = $88c{m}^3$

P = 770 mm

$P_1$ = 880 mm

$V_1$ = ?

T = $T_1$

Using gas equation,

$\frac{PV}{T}=\frac{P_1{V}_1}{T_1}$

$V_1=\frac{770\times 88}{880}$

$V_1$ = $77c{m}^3$

Diminished volume = $88-77$

= $11c{m}^3$
