1 States of Matter

Front

..................... have a definite shape and volume, .............. have a definite volume but take the shape of their container, and ................... have neither a definite shape nor volume.

Back

Solids have a definite shape and volume, liquids have a definite volume but take the shape of their container, and gases have neither a definite shape nor volume.

Front

Describe structure of solids in terms of particle separation, arrangement and motion

Back

In solids, particles are closely packed, arranged in a fixed and regular arrangement and vibrate in a fixed position.

Front

Describe structure of liquids in terms of particle separation, arrangement and motion

Back

In liquids, particles are close to one another, regularly arranged, and move past/ move around one another.

Front

Describe structure of gases in terms of particle separation, arrangement and motion

Back

In gases, particles are far apart, randomly arranged, and move quickly in all directions

................. is the transition from solid to liquid.

..................... is the transition from liquid to gas, it happens at a fixed temperature.

................... is the transition from liquid to gas but it happens to the surface of liquid only, and it can happen at any temperature.

................. is the transition from liquid to solid, and................. is the transition from gas to liquid.

Back

Melting is the transition from solid to liquid.

Boiling is the transition from liquid to gas, it happens at a fixed temperature.

Evaporation is the transition from liquid to gas but it happens to the surface of liquid only, and it can happen at any temperature.

Freezing is the transition from liquid to solid, and condensation is the transition from gas to liquid.

Front

Describe the effects of temperature and pressure on the volume of a gas

Back

Increasing temperature increases the volume of a gas , while increasing pressure decreases the volume of a gas.

Front

Describe and explain diffusion in terms of kinetic particle theory

Back

Diffusion is the process where particles spread from an area of high concentration to an area of low concentration due to their random motion.

Front

Describe and explain the effect of relative molecular mass on the rate of diffusion of gases

Back

Gases with lower molecular mass diffuse faster than those with higher molecular mass, because molecules with lower molecular mass have higher average speed.
