Question

The mercury falls by $\frac{8}{15}$ parts between two standard points on the Celsius thermometer when the boiling water at $100°C$ is allowed to cool to room temperature. Calculate room temperature in Celsius scale.

Answer 1

Step 1: We have

The lowest temperature of the water on the Celsius scale is $0°C$

And the highest temperature of the water on the Celsius scale is $100°C$

So, the gap between two standard points on the Celsius scale =$\left(100-0\right)°C=100°C$

Step 2: To find the required temperature on the Celsius scale

Since the mercury falls by $\frac{8}{15}$ parts between two standard points

So the room temperature will be $\left(\frac{8}{15}\times 100\right)°C$

Hence, the room temperature will be $53.33°C$.
