Question

Which thermometer is showing the lower temperature?

• A.
• B.
• C.
• D.

Answer 1

The correct option is D

The thermometer is a device which is used for measuring temperature. Option D shows lower temperature, i.e. at $0^{\circ }C$. The lower fixed point on Celsius scale is the freezing point of water $\left(0^{\circ }C\right)$ and the upper fixed point is the boiling point of water $\left({100}^{\circ }C\right)$. The lower and upper fixed point on the Celsius scale has a difference of ${100}^{\circ }C$.
