2(a)(i)Easy1 mark

A student compares the rates of temperature increase of two different coloured surfaces. The student uses two thermometers, one of which has a piece of white card attached to its bulb, and one of which has a piece of black card attached to its bulb. Both pieces of card are identical, except for the colour of their surfaces. The student clamps the thermometers so that the bulb of each thermometer is level with the filament of a lamp. The lamp is switched off. Figure 2.1 shows the apparatus.

Figure 2.1, two thermometers clamped on stands facing a lamp, one with a piece of white card and one with a piece of black card taped to its bulb, the white card a distance d1 and the black card a distance d2 from the lamp; the clamp, stand, white card, black card and tape are labelled

The student:

adjusts the distance $d_{1}$ between the lamp and the white card so that the card is 1.0 cm from the lamp
adjusts the distance $d_{2}$ between the lamp and the black card.

Measure, on Figure 2.1, the distance

d_{2}

in centimetres to the nearest millimetre.

The student:

records, in Table 2.1, the temperature shown by each thermometer at time $t$ = 0
switches on the lamp, and at the same time starts a stopwatch
waits for 4.0 minutes
switches off the lamp
takes the reading on each thermometer.

The readings shown by the thermometers at

t

= 4.0 min are shown in Figure 2.2.

Figure 2.2, the scales of the thermometer with the white card and of the thermometer with the black card, each marked in degrees Celsius from below 20 to above 40 with a column of liquid to be read

Record the readings in Table 2.1.

2(b)(i)Easy1 mark

Determine the temperature increase

Δ θ

between

t

= 0 and

t

= 4.0 min for each card.

2(b)(ii)Medium3 marks

Calculate the rate of temperature increase of each card. Use the equation:

rate of temperature increase = \frac{Δ θ}{t}

Give your answers to 2 significant figures. Include the unit in your answer.

rate of temperature increase of white card and of black card, each with its unit

2(c)Medium2 marks

Write a conclusion which compares the rates of temperature increase of the two different coloured cards. Justify your answer using your values from 2(b)(ii).

Your answer

2(d)(i)Easy1 mark

The temperature of each card increases as it absorbs thermal radiation. The procedure used does not produce a fair comparison of the absorbing properties of the two different coloured cards.

Suggest why the procedure does not produce a fair comparison.

Answer

2(d)(ii)Medium1 mark

State why your conclusion in 2(c) would be the same, even if the comparison were fair.
