Match the following substances with their states of matter in room temperature.

Groups:

(a) SOLID

,

(b) LIQUID

,

(c) GAS

• P

• S

• R

• Q

We can describe the movement of particles in solid state as v________

We can describe the arrangement of the particles in solid state as ​ (a)   and form a ​ (b)   .

• touching each other
• regular pattern
• irregular pattern
• compact
• close to each other

Match the following separation of particles with the correct state of matter.

• touching each other

• SOLID

• some are touching, some are not.

• GAS

• far away from each other

• LIQUID

Observe the lab result of diffusion given.

The yellow line forms is ​ (a)   , and it forms on the left side of petri dish because ​ (b)   travels faster. It travels faster because it's mass is ​ (c)   .

• lead iodide
• potassium nitrate
• water
• potassium iodide
• lead nitrate
• lighter
• heavier

Label the heating curve of water with the correct options.
