Boyle's Law says that the volume of a gas varies inversely with the pressure. When the volume of a certain gas is
4 L
, the pressure is
350 kPa
(kilopascals). What is the volume when the pressure is
140 kPa
?
We can use Boyle's Law, which is given by:
P1V1 = P2V2
where P1 and V1 are the initial pressure and volume, respectively, and P2 and V2 are the final pressure and volume, respectively.
Plugging in the given values, we get:
350 kPa x 4 L = 140 kPa x V2
Solving for V2, we get:
V2 = (350 kPa x 4 L) / 140 kPa
V2 = 10 L
Therefore, the volume when the pressure is 140 kPa is 10 L.
To solve this problem, we can use the formula for Boyle's Law which states that the volume of a gas varies inversely with the pressure. The formula is:
P1 * V1 = P2 * V2
Where P1 is the initial pressure, V1 is the initial volume, P2 is the final pressure, and V2 is the final volume.
Given that the initial volume (V1) is 4 L and the initial pressure (P1) is 350 kPa, and we need to find the final volume (V2) when the pressure (P2) is 140 kPa.
Plugging these values into the formula, we have:
350 kPa * 4 L = 140 kPa * V2
Now we can solve for V2:
1400 L * kPa = 140 kPa * V2
Dividing both sides of the equation by 140 kPa:
1400 L / 140 kPa = V2
Simplifying the right side of the equation:
10 L = V2
Therefore, the volume when the pressure is 140 kPa is 10 L.
