Question

A sample of oxygen (O2) of mass 1 g is contained in a 1000 cm³ volume at an initial
temperature of 288.15 K. Take the oxygen to be a perfect gas, with a molar mass of
32 ×10⁻³kg/mol and a constant specific heat ratio of 1.40.
(a) Compute the density (kg/m³) and pressure (kPa) of the gas at the initial state.
(b) Calculate the changes in pressure (kPa) and internal energy (J), when the system
undergoes a process that produces a final volume of 60 cm³ and a final temperature
of 400 K.
