Answer:
1.273 atm
Explanation:
We are given:
P1 = 1 atm P2 = x atm
T1 = 20 degree celsius or 293 k T2 = 100 degree celsius OR 373 k
Since the volume remains constant, we don't have to talk about that
From the Gas equation:
PV = nRT
Since number of moles (n) , Universal gas constant (R) , Volume of the gas (V) are constants
P / T = k (where k is a constant)
Hence we can say that P1 / T1 = k --------------(1)
Also, P2 / T2 = k -------------------------------------(2)
where k is the same constant
From (1) and (2):
P1 / T1 = P2 / T2
Now, plugging the values in this equation
1 / 293 = x / 373
x = 373 / 293
x = 1.273 atm
Therefore, the pressure of CO2 after increasing the temperature to 100 degree celsius is 1.273 atm
