5.

The particles of a substance only move when the substance is heated.

True

False

6.

The higher the temperature, the higher the average of the particles.

7.

What is different for the three states of matter?

8.

The pressure of a gas is produced by its particles hitting the of the container.

9.

The more often gas particles collide with the walls of the container, the lower the pressure.

True

False

10.

11.

How can you find the volume of an irregularly shaped object?

Put it into a measuring cylinder with water and read how much the water level rises.

Weigh it on a balance.

Measure its length with a ruler.

12.

When you put an object into a measuring cylinder with water, the water level rises by exactly the of the object.

13.

To measure its volume, the object only needs to be half under water.

True

False

14.

Density = mass ÷

15.

How do you find the mass of a liquid?

Weigh the empty measuring cylinder, fill it, weigh it again and subtract.

Read the mass from the scale on the measuring cylinder.

Heat the liquid until it boils.

16.

To find the mass of a gas, you can fill a with the gas, close it and weigh it.
