Question

the volume of an ideal gas in a container is 2.0 L what will be the volume of the gas if the pressure on the container is doubled while the temperature is reduced from 400 K to 200 K

Answer 1

0.5 L

Step-by-step explanation:

Answer 2

0.5L

Step-by-step explanation:

To undestand this question you must know two laws: Boyle's law and Charle's law.

Boyle's law states the pressure of an ideal gas is inversely proportional to volume it occupies.

Charle's law states the volume of an ideal gas is directely proportional to absolute temperature.

Thus, when the pressure of 2.0L of gas is doubled, the volume is halved to 1.0 L. Then as the temperature is decreased also in halved from 400K to 200K, the volume is halved from 1.0L to 0.5L
