Why change in internal energy is zero in isothermal process?
$\Delta U = 0$ in the isothermal process only for an ideal gas
Ideal gases by definition have NO potential energy, so the internal energy of ideal gas is only its Kinetic Energy. … We know Kinetic Energy is a function of temperature therefore if the temperature remains constant, kinetic energy remains constant, thus internal energy remains constant and therefore $\Delta U = 0$. …
