Question

1.) A sample of hydrogen gas at 286 K and 0.570 atm occupies a volume of 4.55 L. If the pressure of the gas is increased, while at the same time it is heated to a higher temperature, the final gas volume

a.)will be smaller than 4.55 L.

b.)will be larger than 4.55 L.

c.)could be larger or smaller than 4.55 L depending on the final pressure and temperature.

2.) A sample of oxygen gas at 297 K and 0.297 atm occupies a volume of 3.75 L. If the pressure of the gas is decreased, while at the same time it is cooled to a lower temperature, the final gas volume

a.)could be larger or smaller than 3.75 L depending on the final pressure and temperature.

b.)will be smaller than 3.75 L.

c.)will be larger than 3.75 L

Explanation / Answer

1)

we need to use combined gas law:

P*V/T = constant

that is:

P1*V1/T1 = P2*V2/T2

Here :

P2 > P1

T2 > T1

So, P2/T2 can be greater of less than P1/T1

so, it is impossible to comment on volume
