The diagram shows arrangement of particles in a

• Solid

• Liquid

• Gas

What state of matter is shown in the image?

• Solid

• Liquid

• Gas

From left to right, identify the states of matter

• Gas, Liquid, Solid

• Liquid, Gas, Solid

• Solid, Gas, Liquid

The diagram demonstrate liquid has

• definite shape

• definite volume

• indefinite shape

• Indefinite volume

Answer explanation

Definite shape mean the shape does not change.

Water when poured in a basin take up the shape of the basin (1) and when poured in the glass, it take up the shape of the glass (2).

This mean, liquid has indefinite shape because the shape can change.

The diagram demonstrate that the liquid has

• definite shape

• indefinite volume

• definite volume

Answer explanation

Liquid has indefinite shape as it can change shape according to the container that hold them, but initially 100ml of liquid is poured from the measuring cylinder to the beaker, the volume does not change. It is still 100ml.

Same goes when 100ml from beaker poured to the bowl, the volume stay the same. this show liquid has definite shape

When you buy durian and hide it in the trunk, eventually you can smell it while you are driving. This show the particles move from the region of high concentration to the region of lower concentration. What is this movement called?
