We're asked how long would it take for the sun to cool down if nuclear energy production suddenly came to a hault(adsbygoogle = window.adsbygoogle || []).push({});

This is the question asked in one of my lecture courses given that the radius of the sun is ~ 10^9m, mass ~ 10^30 kg, luminosity ~ 10^26, and G = 6.7x10^-11

Am i correct in assuming we just calculate the total energy of the sun using (3/2)NkT then using the luminosity calc the time?
