The 2 hemispheres are made to clump each other by force so that the sphere is formed which is unseperable in this case is the air pressure more inside the sphere or outside the sphere?

If you are referring to the historical experiment where a scientist placed two hollow hemispheres together, ensured that their contact was air-tight, and then removed the air from between them, the removal of air amounts to a decrease in pressure inside the sphere.

What type of coal probably formed from the greatest pressure?
Anthracite, the hardest coal, forms from the greatest pressure.
Why do vapor bubbles not form in water at room temperature and standard pressure?
we know that water bubbles are formed when external pressure becomes equal to the internal pressure so room temperature is 20 digree to 25 digree and internal pressure deos not equal to external pressure at this temperature so it is clear that vapor bubbles deos not formed in water at room temperature and standard pressure where standard pressure is 760 torr.
When all the liquid has evaporated the vapor totally fills the florence flask and exerts a pressure equal to the atmospheric pressure why?
I'm guessing you are analyzing an experiment where you are determining the molecular mass of an organic liquid. You heated the flask and the liquid evaporated filling the flask, but escaping through a small hole in the covering. 1. Gases always fill the container. So, if the liquid evaporated and formed a gas (vapor), it filled the flask, 2. The pressure on the outside the flask is air pressure. since the vapor isn't pushing off the cover, the pressure is not higher than the air pressure. But since the extra escaped, it cannot be less than the air pressure. Therefore, it is the same.
Why do suction cup stick to wet surfaces better than dry surfaces?
No. How well a suction cup sticks to a surface has to do with how will a seal can be formed on the surface. Rough surfaces will not form good seals compared to smooth surfaces which means that suction cups will not stick as well to rough surfaces as they do to smooth surfaces.
Why rubber suckers sticks on smooth surfaces?
The sucker is dish shaped, when pressed against a smooth surface the air is forced from beneath the sucker.The rubber makes an air tight seal and the air pressure outside is greater than the air pressure beneath the sucker, thus forcing the rubber sucker to 'stick'.

How are igeneous rock formed?
Igneous rocks are formed by heat, pressure and cooling. They can be formed inside a volcano or outside a volcano. If they are formed outside the volcano the rocks are called extrusive igneous rocks, like basalt. If it is formed inside the volcano the rocks are called intrusive igneous rocks, like granite.

(Jaleb) Well not exactally it is formed by pressure but not by fire.
If a metal can is heated with the lid open and then the lid is replaced and the can is allowed to cool what would happen to the can and why?
If the lid formed a seal, it should sag from the outside pressure.
How is metamorphic formed by?
