question 21

Short Answer

The figure shows a pV diagram of a gas for a complete cycle.During part bc of the cycle,1190 J of thermal energy through the process of heating flows into a system,and at the same time the system expands against a constant external pressure of $7.00 \times 10^4 \mathrm {~Pa}$ as its volume increases from $0.0200 \mathrm {~m} ^ { 3 }$ to $0.0800 \mathrm {~m} ^ { 3 }$ Calculate the change in internal (thermal)energy of the system during part bc of the cycle.If the change is nonzero,be sure to indicate whether the change is positive or negative. $The figure shows a pV diagram of a gas for a complete cycle.During part bc of the cycle,1190 J of thermal energy through the process of heating flows into a system,and at the same time the system expands against a constant external pressure of 7.00 \times 10^4 \mathrm {~Pa} as its volume increases from 0.0200 \mathrm {~m} ^ { 3 } to 0.0800 \mathrm {~m} ^ { 3 } Calculate the change in internal (thermal)energy of the system during part bc of the cycle.If the change is nonzero,be sure to indicate whether the change is positive or negative.$
