Context for question 1

A student determines the density of a glass ball.

Context for 1(a)

The student:

pours water into a measuring cylinder until it is approximately half full
places the measuring cylinder of water on a top-pan balance
records the combined mass $m_{1}$ of the measuring cylinder and water.

m_{1}

= 125.6 g

1(a)(i)Easy1 mark

Describe one technique for using a top-pan balance to measure the mass of the measuring cylinder and water to ensure an accurate reading.

Answer

1(a)(ii)Easy1 mark

Figure 1.1 shows the water level in the measuring cylinder. Record the volume

V_{1}

of water in the measuring cylinder.

Answer

1(a)(iii)Easy2 marks

Describe two techniques that the student uses when measuring the volume of the water to ensure an accurate reading.

Technique 1

Technique 2

Context for 1(b)

The student places four glass balls into the water in the measuring cylinder, ensuring no water splashes out. The student records the mass

m_{2}

of the measuring cylinder, water and 4 glass balls.

m_{2}

= 132.8 g

1(b)(i)Easy1 mark

Calculate the mass

m

of one glass ball.

Answer

1(b)(ii)Easy1 mark

The student records the volume

V_{2}

of the water and four glass balls.

V_{2}

= 94

cm^{3}

Calculate the volume

V

of one glass ball.

Answer

1(b)(iii)Easy2 marks

Calculate the density

ρ

of a glass ball. Use your values from 1(b)(i) and 1(b)(ii) and give the unit. Use the equation shown.

ρ = \frac{m}{V}
