Question

A sample of krypton gas at 287 K and 0.808 atm occupies a volume of 4.78 L. If the gas is compressed into a smaller volume, while at the same time it is heated to a higher temperature, the final gas pressure will be lower than 0.808 atm. could be higher or lower than 0.808 atm depending on the final volume and temperature. will be higher than 0.808 atm.

A sample of xenon gas at 310 K and 0.563 atm occupies a volume of 3.90 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 will be smaller than 3.90 L. could be larger or smaller than 3.90 L depending on the final pressure and temperature. will be larger than 3.90 L.

A sample of methane gas at 296 K and 0.572 atm occupies a volume of 2.08 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 could be larger or smaller than 2.08 L depending on the final pressure and temperature. will be larger than 2.08 L. will be smaller than 2.08 L.

Answer #1

1)

we need to use combined gas law:

P1*V1/T1 = P2*V2/T2

here:

V2<V1 and T2>T1

So,

V1/T1 > V2/T2

So,

P1 < P2

Answer: will be higher than 0.808 atm

2)

we need to use combined gas law:

P1*V1/T1 = P2*V2/T2

here:

P2>P1 and T2>T1

So,

Volume of can either increase or decrease

Answer: could be larger or smaller than 3.90 L depending on the final pressure and temperature.

3)

we need to use combined gas law:

P1*V1/T1 = P2*V2/T2

here:

P2>P1 and T2<T1

So,

P1/T1 < P2/T2

So,

V1 > V2

Answer: the final gas volume could be larger or smaller than 2.08 L depending on the final pressure and temperature
