Question

A faulty laboratory thermometer gave the readings
of -2°C and 98°C when inserted into melting ice
and boiling water respectively, both at standard
atmospheric pressure. What is the error when the
same thermometer is used to measure the difference
between two arbitrary temperatures?
А. -1°C
B. 1°C
c. 0°c
D. 2°C​

Answer 1

Answer:

D. 2°C

Explanation:

Temperature of ice is 0°C at standard atmosphere and temperature of boiling water is 100°C at standard atmosphere

0-(-2)=2

100-98=2
