Q.

Raina and Dheeraj measured their body temperature with different thermometers. Raina found it to be 37-degree Celsius and Dheeraj recorded 98.6-degrees Fahrenheit. Why?

Q.

If there are 10 minor divisions between two major divisions, one major division representing $1^{\circ }C$, one minor division will be equal to

1. When the mercury level is in between the divisions

2. When the mercury level coincides with a minor division

3. When the mercury level coincides with a major division

4. Depends on the type of thermometer
