130cmcube of a fas at 20degree Celsius exert a pressure of 750mmhg calculate it pressure if it volume is increased to 150cmcube at 35degree Celsius
pls u need the answer now
Use (p1v1/T1) = (p2v2/T2)
Remember T must be in kelvin.
To calculate the new pressure of the gas, we can use the combined gas law equation:
(P1 * V1) / (T1) = (P2 * V2) / (T2)
Where:
P1 = initial pressure (750 mmHg)
V1 = initial volume (130 cm^3)
T1 = initial temperature (20 degrees Celsius + 273.15) in Kelvin
P2 = final pressure (unknown)
V2 = final volume (150 cm^3)
T2 = final temperature (35 degrees Celsius + 273.15) in Kelvin
First, let's convert the temperatures from Celsius to Kelvin:
T1 = 20 + 273.15 = 293.15 K
T2 = 35 + 273.15 = 308.15 K
Now, plug in these values into the equation:
(750 mmHg * 130 cm^3) / (293.15 K) = (P2 * 150 cm^3) / (308.15 K)
Now, solve for P2:
P2 = (750 mmHg * 130 cm^3 * 308.15 K) / (293.15 K * 150 cm^3)
Calculating this equation will give you the new pressure of the gas when its volume is increased to 150 cm^3 at 35 degrees Celsius.
