Phase Of Matter Flashcards
(22 cards)
3 phase of matter
●Solid
●liquid
●gas
Properties of solid
●fixed form
●high density
●solids have fixed volume
Properties of liquid
●don’t have fixed form
●Not hard
●fixed volume
Properties of gas
●don’t have fixed form
●not hard
●don’t have fixed volume
Diffusion
When it’s has a high concentration to low concentration.
Brownian motions
Movement of particles
Freezing point
Temperature at which liquid turned into solid
Melting point
Temperature at which solid turns to liquid
Boiling point
Temperature at which liquid turned into gas
Measure temperature
Theremometer
Phase change
When substance changes from one physical state to another
Why does the temperature rises
Because the average kinetic energy of particles increase during heating
Why does the temperature decrease
Particles move slower and kinetic energy decrease
Transition heat
Heat produced during phase change take up
What happen from a solid to liquid
1.When the solid is heated the heat is absorbed and converted to kinetic energy
2.At melting point kinetic energy overcomes the intermolecular force.
3. Particles not is fixed position.
What happens from liquid to solid
- Particles loss kinetic energy and move slower
- The particles start to move close
What happens when liquid boils
- Kinetic energy increases and start move faster
- The particles move further
Evaporation
Liquid into gas without boiling
Volatile liquid
Liquid that evaporate at room temperature
Condensation
Gas into liquid
What happens when particles of gas condenses
- Loss heat energy and loss energy and moves slower and moves closer to each other
Sublimation
Substance changes into gas without going through liquid state
