In class we showed that for a Carnot cycle for an ideal gas (Lecture 8, page 10), the following identity follows: Sigmai qi/Ti = q1/T1 + q2/T2 = 0, Where qi, is the (reversible) heat associated with each isothermal step. As we shall see next week, we will be able to identify each of these terms as entropy contributions, DeltaSi = qi/Ti, such that they add up to zero in a cycle, giving...

We have seen that the Carnot cycle can be used to determine the maximum efficiency of a heat engine. The efficiency is defined as the sum of all of the work during the cycle divided by the amount of heat exchanged during the expansion process: efficiency=?1 +?2 +?3 +?3 /?1 Theoretically, the efficiency of the engine can be determined with the hot and cold temperature of the cycle. efficiency = ?h − ?c/ ?h In this problem, we will calculate...

T9D.3 In this problem, you will calculate the efficiency of a Carnot engine without referring to entropy (a) Consider the isothermal expansion in step 1 of the Car- not cycle. Because the temperature of the gas remains constant, work energy that flows out of the gas as it expands must be balanced by the heat energy flowing into the gas. Use this and equation T7.10 for the work done in an isothermal expansion to show that (T9.16) (b) In a...
