What is the definition of pressure quizlet?
Consequently, what is the correct definition of pressure?
Pressure (symbol: p or P) is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. Pressure may also be expressed in terms of standard atmospheric pressure; the atmosphere (atm) is equal to this pressure, and the torr is defined as ?1⁄760 of this.
Subsequently, question is, what is described as the collision of the molecules? The collision theory explains that gas-phase chemical reactions occur when molecules collide with sufficient kinetic energy. The collision theory is based on the kinetic theory of gases; therefore only dealing with gas-phase chemical reactions are dealt with. All molecules are rigid spheres.
Also to know, what causes pressure chemistry quizlet?
Pressure is inversely proportional to volume, or higher volume equals lower pressure. Pressure is directly proportional to temperature, or higher temperature equals higher pressure.
What causes fluid pressure?
Fluid pressure is a measurement of the force per unit area. Fluid pressure can be caused by gravity, acceleration, or forces in a closed container. Pressure increases because as you go deeper, fluid at a lower depth has to support fluid above it as well.
