At 9.°C and 1.40 atm pressure, a sample of helium gas occupies a volume of 5.10 L. The sample is compressed and heated to 60.°C. Calculate the final pressure of the sample, if the final volume is 3.64 L.
Pressure and temperature at the start of compression in a standard diesel cycle are 95 kPa and 300 k. At the end of the heat addition, the pressure is 7.2 MPa and the temperature is 2150 k.
