The volume of a gas in a container varies inversely with the pressure on the gas. If a gas has a volume of 220 cubic inches under a pressure of 17 pounds per square inch, what will be its volume if the pressure is increased to 19 pounds per square inch? (Round off your answer to the nearest cubic inch.)

The final Volume of the gas in the cylinder   = 196.84

Explanation:

Given that the volume of a gas in a container varies inversely with the pressure on the gas.

⇒ P ∝

⇒ P V = constant

=  --------- (1)

Given that = 17

= 19

= 220

⇒

⇒ = 196.84

The final Volume of the gas in the cylinder   = 196.84

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
