No, water cannot be used as thermometric liquid because :

1. It has got high value of specific heat capacity,so, absorbs more of heat to increase small amount of volume.

2. It doesn't have uniform expansion as it shows the phenomenon of anamolous behavior within temperature range of 0C to 4C.

3. It sticks on glass and doesn't give correct reading.

4. It is transparent and can't be easily seen.

5. It's freezing point is 0C and boiling point is 100C. So it measures the small range of temperature...

C denotes the unit of actual/absolute temperature while C denotes the unit of temperature interval or difference or change in temperature.

An actual temperature of 20C is stated as 20C where as the interval of 20 is stated as 20C.

Medicine labels often recommend storing the medicine at a temperature below 86F (i.e. 30C) because higher temperatures can cause the medicine to break down and become less effective. Some medications are more sensitive to temperature changes than others. For example, some medications may be stable at room temperature but become less effective or even expire if they are stored at higher temperatures.

Thermal energy is the energy that is associated with the movement of molecules. At the molecular level, thermal energy is the energy that is associated with the vibrational, rotational, and translational motion of molecules.

All molecules are in constant motion due to the heat energy they possess. The faster the molecules are moving, the higher the temperature of the substance. The energy of these molecular movements increases with temperature. When a substance is heated, the energy of the...

No. The condition of having same temperature of objects when in contact is known as thermal equilibrium in which there is no transfer of kinetic energy of molecules between the objects.

I would prefer to use a cylindrical bulb instead of spherical bulb .

A sphere has the smallest ratio of surface area to volume of any shape. One of the factors of the rate of heat transfer is the amount of surface area contact of the thermometer and the object whose temperature is being measured. By using a cylindrical bulb, rather than a spherical bulb, the time to get an accurate temperature is reduced.
