Mass Density and Volume

Question 1

Define Matter

Answer 1

Matter is anything that occupies space and has a mass

Question 2

Define Mass

Answer 2

How much matter an object contains, measured in g/kg

Question 3

Distinguish between mass and weight, include units.

Answer 3

Mass is the amount of matter in an object. Mass is measured in kilograms (kg). Weight is a force due to the pull of gravity on an object. Weight is a force and so is measured in newtons (N).

Question 4

Describe an experiment used to measure the volume of an irregular object using a measuring cylinder or a eureka can.

Answer 4

Fill the displacement can until the water is level with the bottom of the pipe. Place a measuring cylinder under the pipe ready to collect the displaced water. Carefully drop the stone into the can and wait until no more water runs into the cylinder. Measure the volume of the displaced water.

Question 5

Define density in relation to the particle theory and understand how it differs in solid liquids and gases.

Answer 5

In general, solids are denser than liquids, which are denser than gases. . The particles in the solid are touching with very little space between them. The particles in a liquid usually are still touching but there are some spaces between them. The gas particles have wide distances between them.

Question 6

Use the Density/Mass/Volume triangle to answer questions.

Answer 6

Density = Mass/Volume

Question 7

Define volume and know how to work out the volume of
an object.

Answer 7

Volume is the amount of space a 3D shape takes up. You can work out the volume of a shape by multiplying height × width × depth.
