A team of scientists is conducting tests to measure the boiling point of a liquid using a thermometer in the liquid. The team is
then recording the temperature where the liquid changes from a liquid to a gas rapidly. After 100 trials, the results are 5 degrees
below the expected results. Which next step is most reasonable? (1 point)

O checking the calibration of the thermometer to ensure that it is giving accurate readings
O assuming that the new results are incorrect
O assuming that the previous measurements are incorrect
O checking the insulation of the apparatus to find out if heat is escaping


Sagot :

The most reasonable step to take will be to check the calibration of the

thermometer to ensure that it is giving accurate readings.

Experiments which are done to be give the same results under standard

conditions. Common causes of incorrect results during the analysis of

boiling point of substances include heating the substance too rapidly or

the thermometer not being properly calibrated.

The thermometer is used to measure the temperature and so must be

properly calibrated to give accurate readings.
