B.1 This question concerns the use of different working substances in an engine 2018 (a) Carbon monoxide (CO) and ethene (C2H4) are gases with the same molecular mass: how do you expect their heat capacities to compare, and why? A reversible heat engine involves one mole of diatomic ideal gas cycling around four states labelled a,b,c & d where a is the state of highest pressure. The cycle comprises two isotherms (a-b, c-d) and two isochores (b-c, d-a). [Note: 'isochore'...

Problem 4: Read Appendix 2 below (Sec. 1.4.1 of Kasap) and then solve. A metallic back contact is applied to the CdTe solar cell of Problem 1 using a set up similar to that described in Figure 1.74 (b) on the next page. To form the metallic back contact, two evaporation sources are used, Cu and Au. An initial 3 nm layer of Cu is deposited first and then 30 nm of Au is deposited. After these depositions, the sample...
