Answer 1

thermometer A

Step-by-step explanation:

The range of a thermometer is the difference between the minimum and maximum temperatures that the thermometer can read.

∴ Range of thermometer A = 110° - (-10)° = 120°

Range of thermometer B = 50° - (-10)° = 60°

∴ Range of thermometer A is greatest.
