Show your procedures. Remember to use the correct variables and units. 1. A gas that expands at a constant pressure of 400 kPa from an initial volume of 30 cm to 40 cm. Determine the work and heat if the process was done at constant temperature. The gas is not ideal. 2. At a constant pressure of 250 kPa a gas is compressed from 0.50 m to 0.10 m. Find the work and heat added to or removed from the gas. 3. The temperature of 3.00 mol of an ideal monatomic gas is increased from 450 K to 600 K at constant pressure. Determine (a) the heat added to the gas and (b) the work done by the gas. 4. Suppose 5.5 cm of a gas with y = 1.4 and a pressure of 150 kPa is adiabatically compressed to one third of its initial volume. Find the final pressure of the gas.
