Answer:
T= 265 degree
Explanation:
Given. n = 3
Vf = 0.319m3.
Vi = 0.153m3.
Q = 4.86*10^3 J
For external process, change in internal energy is zero
W= Q= 4.86*10^3
Also work done for isothermal process is given by
W= nRT in(vf/vi)
T= w/nR in(vf/vi)
T = 4.86*10^3/3*8.314in(0.319/0.153)
T = 265degree
