Question

Let's say I have a .5 inch diameter silver hollow sphere, with a .028" wall thickness, and I want to heat the interior of the sphere to 365F ±.2 degrees, and maintain that temperature for approx 15 seconds. I want to power this mini oven with the smallest battery arrangement allowance space of .375: dia. x 2" length. The oven cycle will be manually activated/deactivated.

1. How would you best achieve heating the sphere?

2. Smallest battery arrangement/maximum number of uses/cycles.

I belive that the equations may be , Q = I*T , P=I*V , but i dont really know the equations for temprature (heat) to electricity .
