A student is given four objects, a mass balance and a metre ruler. Which of the objects can he determine the density of, using only the metre ruler and the mass balance?

• Bolt, aluminium and plastic

• Wood, bolt and plastic

• Aluminium, wood and plastic

• Aluminium, wood and bolt

Which piece of equipment is used to measure the mass of an object?

A baker uses a balance to weigh out some ingredients to make bread. She weighs out some white flour, then she weighs out some wholemeal flour. She notices that the reading on the balance is the same for both types of flour.
The baker can conclude that the two flours have the same:

• volume

• density

• weight

• internal energy

The diagram shows a measuring cylinder containing a liquid , and the same measuring cylinder when it is empty.

What is the density of the liquid?

• 6.30 g/cm³

• 3.00 g/cm³

• 0.33 g/cm³

• 0.16 g/cm³

A geologist wants to determine the density of the object shown below.

What needs to be known in order to calculate its density?

• The radius of the base of the cone and the weight of the cone.

• The surface area of the base of the cone and the height of the cone.

• The volume of the cone and the mass of the cone.

• The height of the cone and the mass of the cone.
