Boyle's Law says that the volume of a gas varies inversely with the pressure. When the volume of a certain gas is 2 L, the pressure is 445 kPa (kilopascal:
What is the volume when the pressure is 178 kPa ?
To solve this problem, we can use Boyle's Law formula:
P1V1 = P2V2
Where:
P1 = initial pressure = 445 kPa
V1 = initial volume = 2 L
P2 = final pressure = 178 kPa
V2 = final volume (unknown)
Plug in the given values and solve for V2:
445 kPa * 2 L = 178 kPa * V2
890 kPa*L = 178 kPa * V2
V2 = 890 kPa*L / 178 kPa
V2 = 5 L
Therefore, the volume of the gas when the pressure is 178 kPa is 5 L.
