States of Matter

Question 1

Changes in the States of Matter

Answer 1

Melting / Boiling / Evaporation / Condensing / Freezing / Sublimation / Reserve Sublimation

Question 2

What are the States

Answer 2

Solid- A fixed shape, particles only vibrate, tightly packed

Liquid- Can move freely past each other (flow), takes the shape of the container, quite dense.

Gas- Rapid and free, expands to fill the space, particles far away from each other

Question 3

Process of a Change of State

Answer 3

Solid - Liquid: When a solid is heated for long enough at a certain temperature it vibrates until the particles can no longer hold together

Liquid - Gas: Boiling = The heat forces the intermolecular bonds to break. this process is called vaporization

Question 4

Diffusion

Answer 4

Diffusion is the process that allows us to smell things far away. Particles can travel many kilometres by bouncing off air particles. Spreading of particles in a gas or liquid is know as diffusion

The process is sped up in higher temperatures, particles move from where there is a high concentration to where there is a low one.
