what happens is that the heat gets trapped in the container and it turns foggy
evaporate
When a liquid is placed in a closed container, molecules with sufficient energy can escape from the liquid and turn into gas. This process is called evaporation.
In a closed container, liquid behaves according to the principles of fluid dynamics and thermodynamics. It takes the shape of the container but maintains a constant volume, as liquids are nearly incompressible. As temperature increases, the liquid may expand slightly, and if heated sufficiently, it can produce vapor, leading to increased pressure within the container. However, the liquid itself will remain at a stable level unless it evaporates or is removed.
If a liquid is not in a container it will evaporate.

Pressure in the container gets higher because of the steam deriving from water, and if you do not let the steam out it will probably explode in a short time.

When liquid oxygen is heated, it undergoes a phase change and turns into gaseous oxygen. As it heats up and transitions into a gas, its volume expands significantly. This increase in volume leads to an increase in pressure, potentially causing the container to rupture if not properly controlled.
In distillation, the particles in a liquid mixture are separated based on their boiling points. When the mixture is heated, the component with the lower boiling point vaporizes first, rises, and condenses back into a liquid in a separate container. The remaining components are left behind in the original container.
