Drag/drop the following equations/values into the boxes below and hence determine the
quantities required (note that you can only drop an item into a box with a matching colour).
Please state all values in scientific notation and to the appropriate number of significant
figures.
Note that the following relationships are for an ideal gas with an initial state (P1, V1, T₁) and a
final state (P2, V2, T2) where W is the work done on the gas, Q is the heat transferred to the
gas and AU is the change in internal energy of the gas. Cp and Cy are the heat capacities of
the gas at constant pressure and constant volume respectively.

Q= CPAT
Q = CVAT
Q=-w
Q = nRT In (V2/V1)
W=0
W=-Q
W=-PAV
W=-nRT In (V2/V1)
W= (P2V2-P1V1)
AU=0
AU = W AU=Q+W PV = nRT
(i) Complete the table below for path AC (an isothermal process). Drag and drop items into
the first row and then calculate the values and enter the numbers in the second row.
