Q15MObservations and MeasurementsExperimental ContextsAnalysis, Conclusions and EvaluationFree sample

In this experiment you will estimate the volume of a thermometer.

You are provided with:

a thermometer
a ruler.

(a)

Measure and record to the nearest millimetre the length $l$ of the thermometer, and the width $w$ of the thermometer at the $50^\circ\text{C}$ mark.

$l$ = ______ $\text{mm}$
$w$ = ______ $\text{mm}$

(b)

Calculate the volume $V$ of the thermometer using the equation:

V = \frac{\pi}{4}lw^2

where $\pi = 3.14$ .

$V$ = ______ $\text{mm}^3$

(c)

The volume calculated in (b) is an estimate of the volume of the thermometer.

Explain why:

(i)

the volume calculation is only an estimate

(ii)

the volume calculation is close to the actual volume of the thermometer.

(d)

The thermometer contains a liquid.

Suggest one reason why it is difficult to determine the volume of this liquid.
