Question

Hi can someone help with this:

1) The volume of a gas is 4 m3 when its pressure is 200 kPa. Assuming the temperature does not change, calculate its pressure when the volume is 3 m3 .

2) The pressure of a gas is 1.8 × 105 Pa when its volume is 80 cm3 . Its temperature is constant. Calculate its volume when the pressure becomes 1.2 × 105 Pa.

I'd appreciate if there was working shown

Answer 1

• 2.67 x10 power5 Pascal

Step-by-step explanation:

• pv=nRT
• n, R,T--constant

so, p1v1=p2v2

p2=p1xv1/v2
