Try filling the enclosure with nitrogen instead of normal air.

Vacuole
The fetus is enclosed in the amniotic sac, which is a fluid-filled membrane that provides protection and cushioning during pregnancy.
Matrix
I am assuming you mean an enclosed heater. Oil stay hot longer & does not rust.
Stable electronic configuration is when the valence shell of an element is completely filled (8 electrons) whereas unstable electronic configuration is when the valence shell of an element is not completely filled
Condensation
When dry steam enters a wet steam filled vessel, it can cause the wet steam to condense as the dry steam releases its latent heat energy to the surrounding wet steam. This condensation increases the moisture content in the vessel and may lead to water accumulation.
because they have completely filled electronic configuration.
Vacuoles are the fluid-filled organelles enclosed by a membrane that store various substances such as food, water, and waste in plant and fungal cells. They play a role in maintaining cell turgor pressure and waste management.
A manometer is used to measure pressure in an enclosed container of gas. It typically consists of a U-shaped tube filled with liquid that reacts to changes in pressure inside the container. The liquid level in the arm of the manometer connected to the container will rise or fall based on the pressure, providing a measurement of the gas pressure.
There is no such thing as artificial oxygen. You could probably light a match in an enclosed space filled with oxygen, though.
