## lets consider three planets: Big planet had a radius twice as big as planet, planet has some radius, the exact value won’t matter, Hallf planet has a radius one half that of planet. All of these planets start at the same temperature. The amount of heat energy in a planet at a given temperature is proportional to its volume (five times as much volume at the same temperature is five times as much heat energy) When they all have the same temperature, how much more heat does “big planet” have than “planet”?
