Question

Will it be alright if water or oil is used in the thermometer?

Answer 1

No, it would not be suitable to use water or oil in a thermometer. Water freezes at 0°C and boils at 100°C, so it cannot measure temperatures beyond this range effectively. Oil also does not expand uniformly with temperature and may stick to the tube, giving inaccurate readings. Therefore, substances like mercury or alcohol are preferred because they expand more uniformly and can measure a wider range of temperatures accurately.
