Question

A gas has a volume of 60dm³ when it is under a pressure of 30kpa. Calculate it's volume when pressure changes

Answer 1

Step-by-step explanation:

Given that,

Initial volume = 60dm³

Initial pressure = 30 kPa

We need to find the new volume when pressure changes to 40 kPa (say).

We know that the mathematical relation between volume and pressure is given by :

`(P_1)/(P_2)=(V_2)/(V_1)`

Put all the values,

`V_2=(P_1V_1)/(P_2)\\\\V_2=(30* 60)/(40)\\\\V_2=45\ dm^3`

So, when pressure of the gas increases, its volume get decreased.
