A gas at a pressure of 2.0 atm occupies a volume of 20 liters. If the volume is decreased to 10 liters and the pressure is increased to 4.0 atm, what will be the final volume of the gas?
Answers
The initial condition of the gas can be expressed using the combined gas law:
P1V1 / T1 = P2V2 / T2
where P1 = 2.0 atm, V1 = 20 L, and T1 is the initial temperature (which we will assume remains constant).
If the volume is decreased to 10 L and the pressure is increased to 4.0 atm, the new conditions can be expressed as:
P2 = 4.0 atm, V2 = ?, and T2 = T1
We can rearrange the combined gas law to solve for V2:
V2 = (P1V1T2) / (P2T1)
Plugging in the given values, we get:
V2 = (2.0 atm x 20 L x T1) / (4.0 atm x T1) = 10 L
Therefore, the final volume of the gas is 10 liters.
