Here is Your Answer..!!!

↪Actually welcome to the concept of the THERMODYNAMICS..

↪Basically The ISOTHERMAL PROCESS IS THE PROCESS IN WHCH THE TEMPERATURE OF THE SYSTEM REMAINS CONSTANT ...

↪as we know that ...

↪♢ U = nCv ♢ T

↪since here the T is = ( T2 - T1 ) = ♢T

↪since here the temperature REMAINS the constant ...♢T = 0 (♢T=0)
THUS WE CONCLUDE THAT

↪♢ U = ♢ E = 0

↪SO the internal energy is ZERO
