Question

WHAT IS THE DIFFERENCE BETWEEN ALCOHOL AND MERCURY THERMOMETER

Answer 1

Since alcohol is non toxic, alcohol thermometers are much safer to use than the mercury thermometers. Alcohol thermometers can be used to measure very low temperatures. Sincemercury has a higher boiling point thanalcohol, mercury thermometer can be used to measure high temperatures

Answer 2

$\boxed{\pink{Mercury \: Thermometer: - }}$

• Mercury remains in liquid state for a wide range of temperature.
• It does not stick to glass.

It is relatively easy to see because it's silvery grey colour.

$\boxed{\pink{Alcohol \: Thermometer: - }}$

• Alcohol is cheaper and less harmful than mercury.
• It can measure much lower temperatures (up to - 115°C) than mercury.

$\bold{\green{(Mercury \: freezes \: at \: -38.87 \: degree \: }}\\\bold{\green{celcius)}}$

$\boxed{\red{Disadvantage:-}}$

Alcohol thermometers cannot measure temperatures higher than 78°C, whereas mercury thermometers can measure much higher temperatures.
