states of matter

what is matter anything that occupy's space
what are the three states of matter solids, liquids. gases
what are the properties of a solid. have a definite shape, have a definite volume, does not flow, cannot be compressed,
what are the properties of a liquid does not have a definite shape, have a definite volume, does flow, cannot be compressed
what are the properties of gases does not have a definite shape, do not have a definite volume, can flow, can be compressed
particle theory-solids particles in a fixed position, particles are packed closely together, there are strong forces holding the particles together.
particle theory-liquids particles have more freedom of movement, particles can slide over each other, the forces holding the particles together is weaker than in solids
particle theory-gases the particles in a gas are much farther apart than in liquids or solids, these particles move very quickly into all space available, there are only very weak forces between these particles.
what is diffusion Diffusion is the spreading out of materials due to the movement of their particles
where does diffusion happen the fastest gases, it happens in gases the quickest because it has the most heat energy. diffusion can happen in liquids too just not as fast because the particles are less spread out which means it has less heat energy
can diffusion happen in solids No
what is a change of state When a substances changes from a solid to a liquid or a gas we call this a change of state
what is changing a solid to a liquid called melting
what is changing a liquid to a gas called boiling
is there another name for changing a liquid to a gas, if yes what is it called evaporation
what is changing a liquid to a solid called freezing
WHAT IS THE DIFFERENCE BETWEEN EVAPORATION AND BOILING Evaporation is the changing of a liquid to a gas at the surface of a liquid Boiling is the changing of a liquid to a gas throughout the liquid
what is changing a solid to a gas called sublimation
what is changing a gas to a solid galled deposition
what is the melting point of a substance The melting point is the temperature at which a solid changes to a liquid
what is the boiling point of a substance The boiling point is the temperature at which a liquid changes to a gas throughout the liquid
DOES THE MASS OF A SUBSTANCE CHANGE WHEN THE STATE OF A SUBSTANCE CHANGES? The mass of a substance does not change when you change the state of a substance
WHAT IS A PHYSICAL CHANGE? A physical change is a change that can be reversed and no new substance is formed Examples include: Crushing can Breaking glass Chopping wood
WHAT IS A CHEMICAL CHANGE? A chemical change is a change that cannot be reversed and new substances are formed Examples include: Baking a cake Rusting of iron Burning of wood
SIGNS OF A CHEMICAL CHANGE Colour change Temperature change Production of light Change in taste or smell Formation of bubbles Change in volume
IS THE CHANGING OF STATE A PHYSICAL CHANGE OR A CHEMICAL CHANGE? The change of a state is an example of a physical change
