Pressure is defined as the force exerted per unit area by atoms or molecules colliding with a surface. In gases, for example, the kinetic energy of the moving gas particles results in constant collisions with container walls, creating pressure. The greater the number of collisions or the higher the velocity of the particles, the greater the pressure exerted. Thus, pressure is a direct result of the behavior and interactions of atoms and molecules in a given volume.
What else can I help you with?
How are elements atoms and molecules are related?
Atoms are elements , e.g Hydrogen. Molecules are combinations of atoms, e.g water H2O is the combination of Hydrogen and Qxygen.
How are atoms and molocules related?
Atoms are the building blocks of molecules. Molecules are formed when two or more atoms chemically bond together. Different combinations of atoms can create a wide variety of molecules with unique properties.
How many atoms are found in 9 molecules of nitrogen gas?
At standard temperature and pressure, nitrogen contains two atoms per molecule. Therefore 9 molecules contain 18 atoms.
What is the pressure of helium?
The pressure that there would be if all the non-helium atoms and molecules were taken away.
According to the kinetic theory .?
Gases comprise of molecules/atoms that collide with each other and the walls of a container as they are inconstant and random motion. Gas pressure is influenced by the velocity of these atoms/molecules.
What is related to the motion of atoms or molecules in a substance?
The motion of atoms or molecules in a substance is related to its temperature, with higher temperatures leading to increased motion. This motion affects the state of matter (solid, liquid, gas) that the substance is in, as well as its properties such as density and viscosity. In gases, the motion of atoms or molecules creates pressure.
How are atoms related to molecules in a sample of a compound?
Atoms are the building blocks of molecules. Molecules are formed when two or more atoms chemically combine through bonds. A sample of a compound is made up of these molecules, which in turn are made up of individual atoms.
What is the cause of gas pressure?
By the movement of the atoms/molecules.

What is the partial pressure of helium?
The pressure that there would be if all the non-helium atoms and molecules were taken away.
How many atoms are found in 9 molecules of nitrogen gas?
At standard temperature and pressure, nitrogen contains two atoms per molecule. Therefore 9 molecules contain 18 atoms.
How is the air pressure inside the jar related to the air molecules inside the jar?
The air pressure inside a jar is related to the number of air molecules present. When there are more air molecules in the jar, the pressure increases due to more collisions with the walls of the jar. Conversely, fewer air molecules result in lower pressure.
What is the pressure of helium?
The pressure that there would be if all the non-helium atoms and molecules were taken away.

Is fast sound waves the same as loud soundwaves?
No. The loudness is related to the amplitude - in the case of sound, how much is the pressure difference; or how far the molecules swing back and forth.No. The loudness is related to the amplitude - in the case of sound, how much is the pressure difference; or how far the molecules swing back and forth.No. The loudness is related to the amplitude - in the case of sound, how much is the pressure difference; or how far the molecules swing back and forth.No. The loudness is related to the amplitude - in the case of sound, how much is the pressure difference; or how far the molecules swing back and forth.
