A student is investigating whether using an unmarked thermometer can be used to measure room temperature of a school laboratory.
The student has the following apparatus available:
Unmarked thermometer
250 cm3 glass beaker
crushed ice
water
heatproof mat
clamp, boss and stand
meter rule
Plan an experiment to investigate how to measure room temperature.
( A diagram is not required but you may draw a diagram if it helps your explanation.)
You should
• list the additional apparatus that you would require [1]
• explain briefly how you would carry out the investigation [3]
• Draw a table, with column headings, to show how you would display your readings; you
are not required to enter any readings in the table. [2]
• explain how you would use your readings to reach a conclusion. [3]
• suggest one way how to improve the desired results [1]
