Multiple Choice

Use the following to answer the question: Use the following to answer the question:   -An ideal gas initially at 50ºC and pressure P<sub>1</sub> = 100 kPa occupies a volume V<sub>1</sub> = 3 L.It undergoes a quasistatic,isothermal expansion until its pressure is reduced to 50 kPa.How much does the internal energy of the gas change during this process? R = 8.314 J/mol·K = 8.206 L·atm/mol·K. A) 116 J B) 208 J C) 256 J D) 304 J E) The internal energy does not change during this process.
