Key Words
When vaporization occurs only at the surface of a liquid?
What is evaporation?
It is a description about how some aspects of the natural world behaves under stated circumstances.
What is Law?
The process by which a liquid changes to a gas or vapor.
What is Vaporization?
He discovered an inverse relationship between effusion rates and molar mass.
Who is Thomas Graham?
It describes the force attraction between identical molecules.
What is cohesion?
What is viscosity?
An explanation supported by many experiments; is still subject to new experimental data and can be modified.
What is Theory?
The exothermic process that is the reverse of vaporization.
What is condensation?
Who is Evangelista Torricelli?
The particles in the air move in all direction, and they exert pressure in all directions.
The point on the phase diagram the represents the temperature and pressure at three phases of a substance can coexist.
What is triple point?
It describes the behavior of matter in terms of particles in motion.
What is kinetic-molecular theory?
The pressure exerted by a vapor over a liquid.
What is vapor pressure?
Named the pressure SI unit pascal(Pa).
The process by which a solid changes directly to a gas without first becoming a liquid.
What is sublimation?
A solid whose atoms, ions, or molecules arranged in an orderly, geometric structure.
What is a crystalline solid?
It states that the rate of effusion for a gas is inversely proportional to the square root of its molar mass.
What is the Graham's law of effusion?
The temperature at which a liquid is converted into a crystalline solid.
What is freezing point?
Found that each gas in a mixture exerts pressure independently of the other gases present.
Who is Dalton?
The force of attraction between oxygen molecules.
What is a dispersion force?
Compounds that lower the surface tension of water.
What is surfactants?
It states that the total pressure of a mixture of gases is equal to the sum of the pressures of all the gases in the mixture.
What is Dalton's law of partial pressures?
When a crystalline solid is at the temperature in which the forces holding its crystal lattice are broken and it becomes a liquid.
What is melting point?
The first person to describe the dispersion forces.
Who is Fritz London?
The smallest arrangement of atoms in a crystal lattice that has the same symmetry as the whole crystal.
What is a unit cell?
