In an internal combustion engine, air at atmospheric pressure and a temperature of about 20°C is compressed in the cylinder by a piston to 1/4 of its original volume (compression ratio = 4.0). Estimate the temperature of the compressed air, assuming the pressure reaches 20 atm.

2. Relevant equations

PV=nRT

restated as:(P1V1)/T1=(P2V2)/T2

3. The attempt at a solution

we are told that the initial situation: has a temperature of 20C or 293K, pressure of 1 atm. Set volume equal to 4m3

final situation: temperature=unknown, pressure=20 atm and volume=1m3

I tried putting these numbers in to the formula and got a few different incorrect answers depending on which units I used, such as: 100C, 52.5C, 58.6C

Please help!

Thank you
