what would happen if you had a 5 inch
thick titanium cube, completely full of water, and you heated it up to 1000F?

the titatinium would expand...the water would expand very little.

The water would boil.

Kabooyeeeeeeee! Prolly nothing much, Titanium melts at 3020*F, so you are a third of the way there. How about the dimensions of the cube?

5 inch thick walls, inside open area of a square foot completely full of water.

I dunno.
But if you squeeze it just as you heat it up, it'll shoot further. |

water would turn to steam...increasing the pressure....making it more difficult for further steam to be produced. system would equalize.
just a guess. |

what would be the water temp? if its completely sealed the water would expand and increase pressure inside the cube....

Im betting it would explode. As rogue mentioned, pv=nrt. If n,R stays the same and V stays relatively the same while temp increases then Pressure would increase. Really depends on what type of titanium were talking about i guess since it has a variety of tensile strengths

Probably it'd be mostly water, and whatever small amount of expansion the cube offered would allow a small portion to vaporize to saturated steam, at equilibrium with the water's dew point at that temp. I'd be more concerned with the tensile strength of a 5" thick cross-section of titanium. Thin metal is more likely to expand like a balloon than thick stuff which usually just cracks. With a thick piece, the temperature gradient across the outside (which would be at the flame's temperature) vs. the inside which would remain a constant 100*C (or more if the steam/liquid 2-phase equilib. The temp difference would probably cause the titanium to have a thermal fracture...like when a windshield stone chip turns into a crack when you're blasting the defrost on a bitter cold morning. Compound that the fact that thick metal is less "forgiving" than thin stuff, as mentioned earlier...and looking at the pressure of the steam at its super heated spot on the steam table...It would blow, and BIG!!!!. Most (all?) gases are stored in cylinders at cold, cold temps (a product of both the P vs. T graph and the fixed volume from PV=RT...n is constant)...think how thick normal gas cylinders are. If you tried to store water vapor (gas state) at that high of a temp, the P vs. T graph would have pressures so rediculously high (factors of at least 100)...5" thick wouldn't be close enough... Then again, I'd have to run the numbers and my Thermo book with the explosion/high pressure section is in storage, and *pop* *crackle* *fizzxxzxxzxzzxzxzxzzz* ...hey, where am I? Oooooooooh look, I got a pimple on my ass, I'm gonna' take a video of me popping it DRum |

the water would be in a superheated state, under huge pressure. It also depends on if its distilled or tap water. Tap water would boil because of impurities, but distilled water will stay liquid. What made you think of this anyway?

But wouldn't the titanium expand equally in all directions and therefore actually leave less space for the water and not more?

You cant compress a liquid, so no
