A gaseous air‑fuel mixture in a sealed car engine cylinder has an initial volume of 600.mL at 1.0atm. To prepare for ignition of the fuel, a piston moves within the cylinder, reducing the volume of the air‑fuel mixture to 50.mL at constant temperature. Assuming ideal behavior, what is the new pressure of the air‑fuel mixture?

A diesel engine's piston compresses 16 cm3 of fuel-air mixture into 1 cm3. The pressure changes from 1 atmosphere to 48 atmospheres. If the initial temperature of the gas was 305 K, what was the final temperature?Note: As long as the units for pressure and volume are the same on both sides of the equation, they will cancel. Temperature, however, must be in units of kelvin. Be sure to use the proper number of significant figures.

An air-filled piston-cylinder undergoes a polytropic compression. Initially, the air is at a pressure of 3 bar, temperature of 324 K and the gas occupies a volume of 69 cm3. After compression, the volume is reduced to 17 cm3 and the specific entropy of the air is reduced by  = -0.1152 kJ kg-1 K-1. Estimate the temperature after the compression, give your answer in Kelvin to the nearest whole number.

A sample of gas was heated 50 K initially and increased to 100 K within a given time. The volume is also increased from 2.0L to 3.0L. If the original pressure was 1.2 atm, what is the new pressure?

The original conditions in a container filled with gas at constant temperature are 183 mL and 310 mm Hg. The desired new volume is 90.6 mL. What pressure should be applied?

A container filled with a sample of an ideal gas at the pressure of 1.5 atm. The gas is compressed isothermally to one-fourth of its original volume. What is the new pressure of the gas?
