Q

What happen from a solid to liquid

A

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.

16
Q

What happens from liquid to solid

A
  1. Particles loss kinetic energy and move slower
  2. The particles start to move close
17
Q

What happens when liquid boils

A
  1. Kinetic energy increases and start move faster
  2. The particles move further
18
Q

Evaporation

A

Liquid into gas without boiling

19
Q

Volatile liquid

A

Liquid that evaporate at room temperature

20
Q

Condensation

A

Gas into liquid

21
Q

What happens when particles of gas condenses

A
  1. Loss heat energy and loss energy and moves slower and moves closer to each other
22
Q

Sublimation

A

Substance changes into gas without going through liquid state
