will the cannonball get to a temperature higher than 200 deg C?

Of course it will.

no

Zeroth law states that everything comes to thermal equilibrium.

So your canon ball is at 20 degrees C and the oven is at 200 degrees they'll eventually come to equilibrium.

I'm assuming here that the canon ball isn't exploding and that there isn't some other outside force that's adding heat to the system.

The oven is adding heat to the system. Fucking freshmen get off /sci/

No, though it will likely have a higher specific heat than the air around it, and thus higher thermal energy per unit volume.

>>7739396
No. Think of it like this, you'll heat the cannonball up to 200 degrees, at which point it'll be in thermal equilibrium with the oven so it will just stay at 200 degrees.

>>7739466
It doesn't change the fact that the heat can't exceed 200 degrees you mong.

The cannon ball will settle at the amount of thermal energy corresponding BY DEFINITION to the same temperature as its environment, 200°C.
