Question

25cm3 of gas at 1 atm has a temperature of 20 degree celsis .

When the gas is compressed to 20cm3, the temperature of the gas increase to 28 degree celsis.
Calculate the final pressure of the gas?​

Answer 1

1.28 atm

Step-by-step explanation:

To solve this problem, you need to use the gas laws, more specifically the Combined Gas Law. It is P1V1/T1 = P2V2/T2. Simply plug your values in. But be careful! Make sure you convert your 20 degree C and 28 deg C to Kelvin, as that it the only temperature scale the Gas Laws work with. Upon plugging in your values, you get approximately 1.28 atm.
