Can water in a pressurised contained, which does not allow for the liquid to expand, heat up?

In: Chemistry

Answer 1

This is exactly what a pressure cooker does. Normally, water boils at 100 degrees celsius. With added pressure, it will boil at 120 degrees or even higher, allow for much quicker cooking temperatures.

Here you can find graphs that plot boiling temperature to pressure. Yes, it is possible to heat, it just takes higher temperatures to reach boiling point, because the gas has to stay in a smaller space.
