a faulty laboratory thermometer give the readings of -2°C and 98°C when inserted into melted 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 A -1 B 2 C0 D 2

Answer:
The temperature at which ice starts melting is 0° C at the standard atmospheric pressure.
Also, the temperature at which the water starts boiling is 100° C.
When the faulty thermometer reads the temperature of melting ice as -2° C, it shows a reading that is 2° C lower than the actual reading, i.e., 0° C.
Similarly, when it reads the temperature of boiling water as 98° C, it shows a reading that is 2° C lower than the actual reading of 100° C.
Thus, when it is used to test arbitrary temperatures, it would show a temperature reading which was 2° C lower than the actual reading, i.e., -2.
