chapter 3, Solid Liquid and Gases
Terms in this set (47)
has a definite volume but no definite shape. Particules move around one another freely. Its is also called a fluid, a substance that flows.
Has indefinite shape and indefinite volume.
definite shape and volume; motion limited to vibration
a change from solid to liquid
involves an increase in thermal energy
This determines a fluid's viscosity
fairly strong attractive forces
Types of solids
are made up of crystals
particles are not arranged in a regular pattern
salt, sugar and snow
examples of crystalline solids
plastics, rubber and glass
examples of amorphus solids.
charasteristic property of liquids; is the result of an inward pull among the molecules of a liquid that brings the molecules on the surface closer together. Due to this the surface of water can act like a sort of skin.
another property of liquids; a liquid's resistance to flowing. Its depends on the size and shape of its particles and the attractions between the particles.
Water and vinegar
have realtively low viscosities.
an example of a liquid with high viscosity
increased thermal energy
turns an ice cream into a gooey mess
change from liquid to solid
involves a decrease in thermal energy
the change in the state from solid to a liquid
charasteristic property of a substance; the specific temperature at which melting occurs in most pure substances. Particles of a solid are vibrating so fast that they break free from their fix position.
0 grade C
Melting and freezing point of water.
The change of state from liquid to solid, Is just the reverse of melting
at its freezing temperature
the particles of a liquid are moving so slowly that they begin to form a regular pattern
The change from a liquid to a gas; takes place when the particles in a liquid gain enough energy to form a gas.
Two main types of vaporization
evaporation and boiling
vaporization that takes place only on the surface of a liquid.
an example of evaporation
occurs when a liquid changes to a gas below its surface as well as at the surface
the temperature at which a liquid boils; depends on the pressure of the air above it. The lower the pressure, the less energy needed for the particles of the liquid to escape into the air.
100 grades C
boiling point of water in places close to sea level.
The opposite of vaporization; occurs when particles in a gas lose enough thermal energy to form a liquid.
How clouds typically form
when water vapor in the atmosphere condenses into liquid droplets. when droplets get heavy enough, they fall to the ground as rain.
Colorless gas that is impossible to see.
occurs when the surface particles of a solid gain enough energy that they form a gas; during this process particles of a solid do not pass through the liquid state as they form a gas.
common name for solid carbon dioxide, it can not exist as a liquid so what happen with it is an example of sublimation
the amount of space that matter fills; it is measure in cubic centimeter, millimeters, liters and other units
Volume of a gas
is the same as the volume of its container, because its particles move and fill the space availabe.
is a measure of the average energy of random motion of the particles of a substance. The faster the particles are moving the greater their energy and the higher the temperature.
At room temperature
the particles in a typical gas travel about 500 meters per second, more than twice the cruising speed of a jet plane.
found that when the pressure of a gas at constant temperature is increased, the volume of the gas decreases; when the pressure is decreased, the volume increases.
the relationship between the pressure and the volume of a gas.
The faster the gas particles move
the more frequently they collide with the walls of their container and the greater the force of the collisions.
when the temperature of a gas is increased at constant pressure, its volume increases; when the temperature of a gas is decreased at constant pressure, its volume decreases.
factor kept unchanged when demostrating Cahrles's Law; can be calculated dividing area by force.
a diagram that tells how two variables, or factors that change are related.
Units scientists use to measure gas temperature
Graph of charles's Law
shows that the volume of a gas is direclty proportional to its Kelvin temperature under constant pressure.
