Multiple Choice
Use the following to answer the question:
-An ideal gas initially at 100ºC and pressure P1 = 250 kPa occupies a volume V1 = 4.5 L.It undergoes a quasistatic,isothermal expansion until its pressure is reduced to 150 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) 320 J
C) 575 J
D) 640 J
E) The internal energy does not change during this process.
