States Of Matter Flashcards
What is matter?
Anything that has mass and takes up space. It is made up of particles and can exist in three states: solids liquids and gases.
What is dissolving?
The process by which crystal particles break away from each other and move to occupy the spaces between the water particles.
What is diffusion?
Movement of particles from an area of high concentration to a place of low concentration until evenly distributed
What is brownian motion?
Dust particles in the air and pollen particles in the water can be seen moving by being bumped into air and water particles respectively
What is osmosis?
Movement of WATER particles from an area of high concentration to a place of low concentration until evenly distributed across a selectively permeable membrane
What are the particles, force of attraction, movement of particles, kinetic energy and effect of heating in solids?
Packed closely together, the force of attraction is strong, the particles do not move, small amounts of kinetic energy and melting point becomes liquid.
What are the particles, force of attraction, movement of particles, kinetic energy and effect of heating in liquids?
Packed fairly close together, force of attraction is moderate, particles move within the liquid, more kinetic energy than in solids and boiling point becomes gas.
What are the particles, force of attraction, movement of particles, kinetic energy and effect of heating in gases?
Widely separated, force of attraction is weak, particles move at great speeds, great amount of kinetic energy and heating makes it expand and causes warming effect.
What is melting?
Solid to liquid.
When heated the solid particles gain kinetic energy and the forces of attraction weaken so the solid melts at the melting point a substance can exist in both solid and liquid states.
What is liquid to gas?
Evaporation.
When heated the liquid particles gain kinetic energy and the forces of attraction weaken and evaporation takes place at the boiling point the substance exists in both liquid and gaseous states.
What is gas to liquid called?
Condensation
When a gas is cooled the particles lose kinetic energy and attraction strengthens and condensation takes place.
What is liquid to solid called?
Freezing.
When a liquid is cooled the particles lose kinetic energy and attraction strengthens
What is gas to solid called?
Deposition.
This direct change happens when gas particles become very cold and become a solid without going through liquid state.
What is solid to gas called?
Sublimation.
This direct change happens when solid particles break off with enough energy to become a gas.
