There's .1 mole of an ideal gas trapped in a cylinder with a movable piston.
If Pi= Pf= 5000Pa, Vi= .04 m^3, Vf= .08m^3, Q=500J,,,Find W, change in (U), Ti and Tf.
change in U = Q+W
W= -p change in V
The Attempt at a Solution
change in U = 700J
Tf= i don't know how to get Ti and Tf... I am not sure whether 200J and 700J are right either..
PLease help me!!
