Question

A gas confined by a piston expands isobarically at 40 kPa. When 21,000 joules of heat is absorbed by the system, its volume increases from 0.13 m3 to 0.4 m3. What work is done on the system and what is the change in internal energy?

Work Done by the System =  [Num]Joules

Internal Energy Change =  [Num]Joules

A gas confined by a piston expands isobarically at 40 kPa. When 21,000 joules of heat is absorbed by the system, its volume increases from 0.13 m3 to 0.4 m3. What work is done on the system and what is the change in internal energy?

Work Done by the System =  [Num]Joules

Internal Energy Change =  [Num]Joules

Explanation / Answer

Work done = 40*1000*0.27 = 10800 J

Internal Energy of System is 21000-10800 = 10200 J
