How will stiff magma create an explosive eruption?
The more viscous or "stiff" types of magma usually contain more trapped gasses. When the magma reaches lower pressure near the surface, the gasses expand explosively, blasting ash and pumice into the air.
What is the partial pressure of a gas in a mixture of gasses?
The pressure exerted by one gas in a mixture
What is the partial pressure of gas in a mixture of gasses?
The pressure exerted by one gas in a mixture
How does temperature create a high pressure area and a low pressure area?
Heat affect the gasses' molecules and atoms which make it spread and expand which increases the volume. If the volume is constant as in a closed system then the pressure will increase and decrease along with temperature in a extrusive relation.
What is the difference between hydraulics and pnuematics?
Hydraulics are powered by liquids under pressure and pnuematics are powered by gasses, usually air, under pressure. Both liquids and gasses are fluids.
Why gasses exert pressure?
As the molecules in the gas move, they collide with the container they are within. These collisions is what we call pressure.
How are gasses made?
By heating up above boiling point (at normal pressure)
How the atoms react in air pressure?
'atoms' cannot 'react' to air pressure for air pressure is generated from atoms (oxygen, noble gasses, water).
Why prevents stars collapsing under the force of their own gravity?
The pressure of the fusing gasses
Why do chemists study pressure and temperature of gasses?
Because gasses have no fixed melting and boiling point, they don't have fixed shape and volume. They also have no conductivity or magnetic properties.
Fluids create high or low pressure?
fluids create low pressure.
What are the structure and atmosphere of the earth?
It consists of various gasses held close to the surface of the Earth by gravity. Since it consists of gasses it has no structure, but the weight of the upper (all relative) gasses press down on the lower gasses: compressing them. Thus the pressure increases as you get closer to the surface (actually the center of the planet).
