the phase is the temperature at which a solid turns to a liquid state
what is melting point
a graph that demonstrates the pressures versus temperature that shows the phases a substance
what is phase diagram
the law that declares the rate of effusion of a gas would be inversely proportional to the square root of its molar mass?
what is Graham's law of effusion
the measure of average kinetic energy of particles?
what is Temperature
the measurement of the liquid's flow resistance.
What is viscosity
the temperature at which liquid turns to vapor?
what is boiling point
the energy needed to increase the surface are of a liquid
what is surface tension
describes the behavior of matter through their particles in motion
what is Kinetic molecular theory
They are attractions that happen between oppositely charged regions of polar molecules.
What is dipole-dipole forces
the smallest arrangement of atoms in a crystal lattice that has the same symmetry as the whole crystal
What is unit cell
the temperature at which a liquid becomes a solid?
what is freezing point
happens between molecules containing a small, high electronegative atom like fluorine, oxygen, or nitrogen. stronger compared two intermolecular forces
what is hydrogen bonds
the sum of all the gases’ pressures in a mixture is equivalent to the total pressure of a mixture of gases
what is Dalton’s law of partial pressures
a SI unit of pressure and commonly seen to appear with things related to gas or air pressure.
what is pascal
device used to measure atmospheric pressure
what is barometer
the point where gas looses its energy and velocity turning the gas matter into a liquid?
what is Condensation
when the particles are not arranged in a regular, repeating pattern
what is amorphous
How many phase changes are there?
Six - melting, freezing, condensation, evaporation, sublimation, deposition
The forces are Tied back to the oxygen molecules being boded together or having a force of attraction. They tend to be weaker.
what is dispersion forces
equivalent to 760 mmHg used to report air pressure
what is atmosphere
the phase changing a substance from gas vapor to a solid making it the reverse of sublimation?
what is Deposition
solids that contain atoms, ion, or molecules arranged in a orderly structure
what is crystalline solids
Which element is a good illustration of how an element can exist in various forms?
Carbon
