प्रश्न
Swathi kept a laboratory thermometer in hot water for some time and took it out to read the temperature. Ramani said it was a wrong way of measuring temperature. Do you agree with Ramani? Explain your answer.

उत्तर
Yes, I agree with Ramani.
- Laboratory thermometer does not have a kink. So, when Swathi takes out the thermometer, the level can go back because of absence of kink.
- So Swathi should note the reading when the thermometer bulb has surrounded by hot water.
