Density of Regular Objects

A student is told to measure the density of a liquid and also of a large cube of metal.

Which pieces of equipment are sufficient to be able to take the measurements needed?

• balance, measuring cylinder and ruler

• balance and thermometer

• measuring cylinder and ruler

• measuring cylinder, ruler and thermometer

The diagram shows a rectangular block of density 2g/cm³. What is the mass of the block?

• 2 g

• 6 g

• 14 g

• 24 g

A measuring cylinder containing liquid is placed on a top-pan balance. The apparatus is left overnight and some of the liquid evaporates. The diagrams show the readings. What is the density of the liquid?

• 0.875g/cm³

• 1.14g/cm³

• 1.40g/cm³

• 1.42g/cm³

Diagram 1 shows a measuring cylinder containing water. Five identical steel balls are now lowered into the measuring cylinder. Diagram 2 shows the new water level in the cylinder. what is the density of these metal balls if one ball is 9 gram.

• 0.3 g/cm³

• 1.5 g/cm³

• 0.64 g/cm³

• 1.13 g/cm³

The diagrams show the readings on a measuring cylinder before and after a small metal cube is added. if the mass of the cube is 12 gram, find the density of the cube.

• 2 g/cm³

• 4 g/cm³

• 6 g/cm³

• 8 g/cm³

The diagrams show an experiment to determine the density of a stone. the mass of the measuring cylinder before the stone placed in it is 40 gram and the mass of the measuring cylinder after placing the stone is 55 gram. what is the density of the object

• 3 g/cm³

• 5 g/cm³

• 7.85 g/cm³

• 0.2 g/cm³

An unopened bottle of olive oil has

a mass of 0.97 kg. The empty bottle

has a mass of 0.51 kg.

Calculate the mass of the olive oil. if the volume of the oil is measured as 515 cm³ , find the density of the liquid.

• 0.75

• 0.89

• 1.12

• 0.98

A measuring cylinder contains 30 cm³ of water.

A solid metal ball is dropped into the water and the water level rises to 60 cm³. The mass of the ball is 150 g. What is the density of the metal from which the ball is made?

• 2.5 g/cm³

• 0.4 g/cm³

• 5 g/cm³

• 0.2 g/cm³

A measuring cylinder contains 40 cm³ of a liquid. Some more of the liquid is added until the liquid level reaches the 70 cm³ mark. if the mass of the liquid increases by 45 gram, what is the density of the liquid?

• 1.5 g/cm³

• 0.67 g/cm³

• 0.64 g/cm³

• 1.1 g/cm³

A liquid has a volume of 100cm³ and a mass of 85g.

The density of water is 1.0g/cm³. How does the density of the liquid compare with the density of water?

• Its density is higher than that of water.

• Its density is lower than that of water.

• Its density is the same as that of water.

• It is impossible to say with only this data.
