Question

Under the condition that the tempernture remains constant, the volume of gas is inversely
porpotional to its pressure. If the volume
of gas is 630 cubie cm of the pressure of
360mm
then what will be the
pressure of the gas if its volume is
720 cubic cm at the same temperature.
​

Answer 1

Step-by-step explanation:

Given

Temperature remains constant and

Volume of gas is inversely proportional to its pressure.

So, let x=Volume of gas=630 cubic cm

and y=Pressure=360mm

Let pressure of gas be a mm

and their volume = 720 cm

3

So, 630×360=a×720

a=

720

630×360

=315

∴ Pressure of gas is 315 mm of mercury.
