Year 10 Particulate of Matters Chemistry

State the process of 4

• melting

• boiling

• feezing

• condensation

State the freezing point using heating curve

Why temperature do not rise during boiling?

• energy use to increase intermolecular force

• energy use to break intermolecular force

• energy use to overcome electrostatic forces of attraction

• energy use to form electrostatic force of attraction

What happens when heat is applied to the solid zinc ?

• gain heat and kinetic, vibrates faster, expand a little

• expand a little and break intermolecular force

• energy use to break intermolecular force, increase intermolecular space

• energy release increase intermolecular force

When liquid freeze to solid, particles lose kinetic and heat energy...

• increase bonding, decrease space

• decrease intermolecular force, increase intermolecular space

• increase electrostatic force of attraction, decrease intermolecular space

• increase intermolecular force, decrease intermolecular space

When you add impurities, melting point ...

• decreases

• increases

When you add impurities, boiling point ...

• decreases

• increases

define precipitate

• Reaction which an insoluble salt is prepared from solutions of two soluble salts

• Is formed when a substance (solute) dissolves into another substance (solvent)

• Mixture containing small particles of an insoluble solid, or droplets of an insoluble liquid, spread (suspended) throughout a liquid

• Two or more substances mixed together but not chemically combined- substances can be separated by physical mean.

define suspension

• Reaction which an insoluble salt is prepared from solutions of two soluble salts

• Is formed when a substance (solute) dissolves into another substance (solvent)

• Mixture containing small particles of an insoluble solid, or droplets of an insoluble liquid, spread (suspended) throughout a liquid

• Two or more substances mixed together but not chemically combined- substances can be separated by physical mean.

define saturated solution

• more solute can be dissolve at a given temperature

• solute that cannot dissolve in a given temperature

• no more solute can dissolve at a given temperature

• maximum solute that can dissolve at a given temperature
