Question

The gas in a balloon has P=100000 pa and v=0.0279 m^3. if the pressure increases to 120000 pa at constant temperature, what is the new volume of the balloon?( hint:N and T are constant.) also (Unit=m^3)

Answer 1

0.02325 m^3

Step-by-step explanation:

P1 = 100000Pa , v1 = 0.0279m^3

P2= 120000Pa . V2 = ?

as mass and temperature are constant using ratio method for Boyle'slaw

P2V2= P1V1

or V2= P1V1/P2

V2 = 100000×0.0279/120000

V2= 0.02325 m^3
