How do you know determine if internal energy equals 0?

Change in internal energy would be 0 for an ideal gas in the case when there is constant temperature (isothermal). Because change in temperature is 0, then change in internal energy is 0, as the two variables are related through the equation: deltaU = 3/2*n*R*deltaT.
