Question

If X and Y represent the lower and upper limits of the temperature range of the given thermometer then the value of X and Y will be:

• A. $X=35°C,Y=42°C$
• B. $X=0°C,Y=100°C$
• C. $X=10°C,Y=110°C$
• D. $X=-10°C,Y=110°C$

Answer 1

The correct option is D $X=-10°C,Y=110°C$

The given thermometer is a laboratory thermometer because it has no kink. A laboratory thermometer has a temperature range of $-10°C$ to $110°C$.
So, the lower limit (Y) of the lab thermometer will be $-10°C$, and the upper limit will be $110°C$.
