A hollow metal sphere is totally filled with water and sealed.
It is then heated uniformly.
What happens to the pressure of the water? (The coefficient of expansion of
the metal is higher than that of the water.)
If the pressure drops initially (as I think it must ) what happens as the
whole thing gets hotter.

The water will start to release gas, since its ability to hold gas in
solution is reduced with increasing temperature. This means the increase
in temperature will have a less marked effect when gas is present.
Then as the temperature is further increased, the water will boil and the
pressure will start to climb with increasing temperature.
