Energy And Matter

Front 1

State of Matter

Back 1

Materials can be classified as solids, liquids, or gases based on whether their shapes and volumes are definite or variable.

Front 2

Solid

Back 2

Is the state of the matter in which materials have a definite shape and a definite volume.

Front 3

Liquid

Back 3

Is the state of the matter in which material has a definite volume but not a definate shape.

Front 4

Gas

Back 4

Is the state of matter in which a material has neither a definate shape nor definite volume.

Front 5

Kinetic Theory

Back 5

Is the energy an object has due to its motion.

Front 6

Behavior of Gases

Back 6

Each atom moves in a straight line until it collided with another atom or with the wall of a container. During a collision, one atom may lose kinetic energy and slow down while the other atom gains kinetic energy and speeds up. There are forces of attraction among all particles, but particles in a gas are apart and moving fast are too weak to have an effect.

Front 7

Kinetic Theory of Gases

Back 7

The constant motion of the particles in a gas allows a gas to fill a container of any shape or size.

Front 8

Behavior of Liquids

Back 8

In a liquid, there is a kind of tug of war between the constant motion of particles and the attraction among particles. Because forces of attraction limit the the motion of particles in a liquid, the particles in a liquid can not spread out and fill a container. The attraction between the particles in a liquid affect the movement liquid can flow, but attraction of particles keeps volume same.

Front 9

Behavior of Solids

Back 9

Solids have a definate volume and shape because particles in a solid vibrate around a fixed location. Strong attraction among the atoms restrict Their motion and keep each atom in a fixed location relative to its neighbors each atom vibrates around a location but it does not exchange places with neighboring atoms.

Front 10

Pressure

Back 10

Is the result of a force distributed over an area.

Front 11

Gas Pressure and Temperature

Back 11

Raising the temperature of a gas will increase its pressure of the volume of the gas and number of particles are constant.

Front 12

Gas Pressure and Volume

Back 12

Reducing the volume of a gas increases its pressure If the temperature of the gas and the number of particles are constant.

Front 13

Gas Pressure and Number of Particles

Back 13

Increasing the number of particles the pressure of a gas if the temperature and volume are constant.

Front 14

Charles's Law

Back 14

States that the volume of a gas in directly proportional to its temperature in Kelvins if the pressure and the number of particles of the gas are constant.

Front 15

Absolute Zero

Back 15

Is the temperature of O Kelvins or Ok. It is approximately - 273.15 Celcius.

Front 16

Boyle's Law

Back 16

States that the volume of a gas is inversely proportional to its pressure if the temperature and the number of the particles are constant. ( If the volume decreases, the pressure increases ; if the volume increases, the pressure decreases.)

Front 17

Gray - Lussac's Law

Back 17

States that the pressure of a gas is directly proportional to its temperature if the volume of the gas and number of miles of gas particles remain constant ( if pressure increases, then temperature increases; if pressure decreases then temperature decreases.)
