Four different thermometers were used to measure the temperature of a sample of pure boiling water. the measurements are recorded 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.
