The phase diagram shows the state of water (H2O) under very high pressure (X-axis) and temperature conditions (Y-axis). These conditions apply in the interior of the ice planets Uranus and Neptune ...

Figure 1: Proposed phase diagram of lithium over a wide pressure–temperature range. Apart from bcc and fcc, the phases are labelled with their structural types using the Pearson notation.

This diagram, which plots temperature on one axis and pressure on the other, reveals the most stable phase of water at a given pressure-temperature condition. “These simulations are usually very ...

"In the phase diagram, we can draw the pressure and temperature in the interiors of Uranus and Neptune. Here, the pressure can roughly be taken as a measure of the depth inside.

An example of a discontinuous phase transition is when liquid water reaches 100ºC and boils into a gas at normal atmospheric pressure. However, as pressure increases, ... The resulting ...
