Four different thermometers were used to measure the temperature of a sample of pure boiling water. The measurements are recorde
d in the table below.
Thermometer
Temperature Temperature Temperature
Reading 1 Reading 2 Reading 3
100.1°C 99.9°C 96.9°C
100.4°C 102.3°C 101.4°C
90.0°C 95.2°C 98.6°C
90.8°C 90.6°C 90.7°C
The actual boiling point of pure water is 100.0°C
What can be concluded from the data about the reliability and validity of the thermometers?
A.
Thermometer Y has the highest validity
B.
Thermometer Z is the most reliable.
C.
Thermometer X has the highest validity.
D.
Thermometer W is the most reliable.
The thermometer can be defined as a device which is used measure the temperature of the substance.
The thermometer Z is more reliable because the the readings are similar and close to the original temperature of the water.
The readings like 100.4°C 102.3°C 101.4°C are very close to 100°C. Hence, it can be said so that the thermometer Z is reliable as there is not much deviation in the original reading and observed reading.
