Robert Hooke (1635–1703) of London was the first to suggest using the freezing point of water as a lower fixed point. It … It freezes at 0C and boils at 100C and hence the range is not very wide. Water cannot be used in thermometer because of its higher freezing point and lower boiling point than other liquids. Why is melted paraffin was allowed to drop a certain height and not just rub over the skin? There are four different thermometric scales that are used. What Is The Difference Between Evaporation And Vaporization? It is thus comparatively harder to make any readings with it.

The use of the mercury thermometer is contraindicated due to health risks, such as respiratory problems or skin damage, but there are also currently glass thermometers similar to the old mercury, called analog thermometers, which do not have mercury in their composition and can be used … According me water has higher freezing point and lower boiling point than other thermometric liquids. It's thermal expansion is not as linear as other liquids available. K) (at 25 °C). The most metals are solids at room temperature but the mercury is liquid form because it has high coefficient of expansion. Its expansion is not uniform over a wide range of temperatures. It is volatile and hence vapours apply a pressure on the surface thereby affecting reading. The disadvantages includes, it is fragile and the fluid contained inside the tube may be toxic.

The melting point of water is 0 o c but when you see mercury freezing point (melting point) -38.83 o c and the boiling point of the mercury is 356.73 o c. The boiling point of water is 100 o c. So based on this criteria the mercury is having the temperature reading capacity compared to water. You may need to download version 2.0 now from the Chrome Web Store. A PH of... Why Is Frozen Water Less Dense Than Liquid Water? This is the working principle of every sealed, liquid-containing thermometer. 2. Alcohol has a low boiling point of about 78 o C and therefore cannot be used to measure high temperatures. The thermal expansion of water is from. Why Water Cannot Be Used As A Thermometric Liquid?
