What is the definition of matter?

• Matter is the absence of space.

• Matter is anything that has mass and occupies space.

• Matter is a type of energy.

• Matter is anything that can be seen or touched.

What are the three states of matter?

• rock, water, air

• solid, liquid, air

• solid, liquid, gas

• solution, aerosol, vapour

What is the state of matter that has a definite shape and volume?

• Gas

• Liquid

• Solid

What is the state of matter that takes the shape of its container but cannot be compressed?

• solid

• liquid

• gas

Which property of gas is true?

• Gases do not occupy space.

• Gases cannot be compressed.

• Gases have a definite shape and volume.

• Gases take the shape of the container they are in.

Describe how the properties of liquids differ from those of gases.

• Liquids can be compressed easily, while gases cannot be compressed at all.

• Gases have a definite shape and volume, while liquids do not have a definite shape.

• Liquids have a definite volume but gases do not as gases can be compressed.

• Liquids have no definite volume and take the shape of their container, while gases have a definite volume.

How do you measure the mass of an object?

• Estimate the mass by its volume.

• Use a thermometer to measure the mass.

• Weigh the object using a ruler.

• Use an electronic balance to measure the mass of an object.

Which apparatus cannot be used to measure the volume of a liquid?

• beaker

• measuring cylinder

• weighing scale

• syringe

What happens to the volume and mass of a gas when it is compressed?

• The volume of a gas increases but mass remains the same when it is compressed.

• The volume of a gas decreases but mass remains the same when it is compressed.

• The volume and mass of a gas both decreases when it is compressed.

• The volume and mass of a gas both remain the same when it is compressed.

How can you determine the volume of a small rock?

• Use a ruler to measure the height and width, then calculate using a math formula.

• Weigh the rock using an electronic balance.

• Put the rock into a known amount of water in a measuring cylinder. The change in water level is the volume of the rock.
