Question B: A sample of 1.00 mole of a diatomic ideal gas is initially at temperature 265 K and volume 0.200 m³. The gas first undergoes an isobaric expansion, such that its temperature increases by 140.0 K. It then undergoes an adiabatic expansion so that its final volume is 0.420 m³. i. Sketch a PV diagram for the two-step process, including labeled initial, final, and intermediate states, and a two- part curve/path with an arrow indicating direction. Label the initial state "i", the final state "f", and the intermediate state "b". Write down the known values for P, T, and V at each point, e.g. T₁ = 265 K, and T = 405 K. W (B.1) What is the initial pressure of the gas, P₁, in pascals [Pa]? Pa (B.2) What is the total heat transfer, Q, to the gas, in joules []?
