The distance between the fixed point of a celsius thermometer is20cm. what is the temperature when the mercury level is 4.5cm above the lower mark?

22.5°C

Explanation:

Given height of Celsius thermometer is 20 cm.

As we know the limit of a Celsius thermometer is 100°C

It is given that total height of thermometer is 20 cm.

So, this limit that is 100°C should be equal to 20 cm.

Now, we want to find the temperature when the level of mercury was 4.5 cm.

°C

°C

Hence, we have 22.5°C temperature in Celsius thermometer when height of mercury is 4.5 cm above the lower mark.
