If a sun burns hotter with greater mass, does adding a tonne of water make it hotter?

I suspect the answer here is yes, and there’ll be a lot more hydrogen and oxygen in the star afterwards… but really I’m posting to see what a proper scientist will say.

Am keen to know if this would pretty much include anything. For example, if I gathered a great enough density of chocolate eclairs in one place, would that become a star?

I believe anything lower from iron will make a star, when enough material added. Of course, one material from iron will give a much smaller lifespan for a star rather than hydrogen only.

I think that an iron ball wouldn’t start a fusion. Might just jump right to a black hole if you added even more iron 🤔

Damn now my curiosity is piqued.

So let’s theoretically gather together an almighty ball of iron.

As you add more, would it’s own gravity cause the density to increase to a point where it would collapse into a black hole?

Would chocolate eclairs achieve fission? I need to submit these to Randall Munroe.

I believe so!

I assume chocolate is made of lighter elements than iron so yeah, a big chocolate ball enough would become a star!

Yum 🤤

I don’t know how long it stays edible 😅

And eventually you’d be crushed by the growing gravitational pull of this chocolate ball!

There is a way to find that out. We can use Schwarzschild radius to find the point at which an objects radius crosses the event horizon and thus becomes a black hole; Rs=2GM/c^2^, Rs being the Schwarzschild radius, G being the gravitational constant (6.67xe^-11^), M being the things mass, and c being the speed of light.
