A sample of carbon dioxide gas occupies a volume 3.50Lat 125kPa pressure. What pressure would exert if the volume was decreased to 2.00L at constant temperature

Answer 1

Using the ideal gas law equation, we can determine the new pressure of the carbon dioxide gas.

PV = nRT

Where:
P = pressure
V = volume
n = number of moles
R = ideal gas constant
T = temperature

Since the temperature is constant, we can set up a ratio of the initial pressure and volume to the final pressure and volume:

P1V1 = P2V2

(125 kPa)(3.50 L) = P2(2.00 L)

P2 = (125 kPa)(3.50 L) / 2.00 L
P2 = 218.75 kPa

Therefore, if the volume of the carbon dioxide gas is decreased to 2.00 L at constant temperature, the pressure exerted would be 218.75 kPa.
