A gas at a certain temperature has a pressure of 150 kPa, and its volume is 1.5 m³. If the gas undergoes an isothermal expansion to 2.5 m³, what will be the new pressure assuming it stays at the same temperature?
💡 Hint: Apply the ideal gas law while keeping temperature constant.
A gas is compressed isentropically to half its volume, starting from a pressure of 100 kPa. What is the pressure after compression if k = 1.4?
💡 Hint: Remember to take into account the value of k for your calculations.
