An Ideal Gas Undergoes the Process $a \rightarrow b \rightarrow c \rightarrow a$

question 65

Multiple Choice

An ideal gas undergoes the process $a \rightarrow b \rightarrow c \rightarrow a$ shown in the $p V$ diagram. In the figure, $P _ { a } = P _ { C } =$ $240 \mathrm { kPa } , V _ { b } = V _ { c } = 40 \mathrm {~L} , V _ { a } = 15 \mathrm {~L}$ , and $P _ { b } = 400 \mathrm { kPa }$ . How much heat is gained by the gas in this $a$ $\rightarrow b \rightarrow c \rightarrow a$ process?

• A) \(1500 \mathrm {~J}\)
• B) \(2500 \mathrm {~J}\)
• C) \(1000 \mathrm {~J}\)
• D) \(2000 \mathrm {~J}\)
• E) \(3000 \mathrm {~J}\)
