Mercury freezes at around -39 degrees Celsius, so below this temperature, the mercury in the thermometer would solidify and no longer be able to expand and contract with changes in temperature, rendering the thermometer unusable.
On a thermometer, temperatures above zero are written as positive and below zero as negative. How will a reading of 3 degrees celsius below zero be written?
15 degrees Celsius below 0 is -15 degrees Celsius.
At 30 degrees Celsius, water, ethanol, and acetone are common examples of liquids. Each of these substances have a melting point below 30 degrees Celsius, allowing them to exist in liquid form at that temperature.
Five degrees below zero on a Celsius scale is -5 degrees Celsius.
16 degrees below freezing, as the freezing point of water is 0 degrees Celsius.
Mercury thermometers can go past -40 degrees Celsius. However, mercury freezes at temperatures below -39 degrees Celsius, so the thermometer will not be able to register lower temperatures accurately.
When very cold, at or below -39 degrees Celsius (-38 degrees Fahrenheit) mercury is a solid.
Yes, mercury is a liquid at 150 degrees Celsius. Mercury is a unique element that remains in liquid form at normal room temperature and only solidifies at temperatures below -38.83 degrees Celsius.
On a thermometer, temperatures above zero are written as positive and below zero as negative. How will a reading of 3 degrees celsius below zero be written?
Mercury freezes at temperatures lower than -40°C, which are commonly reached at the South Pole. This would render the thermometer unusable in that environment. Additionally, mercury is toxic and poses a risk if the thermometer were to break in such a remote location.
No, 30 degrees Celsius below zero is -30 degrees Celsius.
Well, Mercury can't freeze or evaporate at the temperature recorded on a standard thermometer. If water were used in a thermometer, we wouldn't be able to record any temperatures below its freezing point (0 degrees Celsius) or above its boiling point (100 degrees Celsius. Mercury has many unique properties. It is a liquid metal and as a metal it expands when heated. When the mercury is heated it rises in the thermometer. And markings on the glass indicate the temperature. Water does not do this. But now in this Digital World mercury has been loosing its importance just because everyone wants to use Digital Technology which provide fast and accurate reading and also safe in use, no doubt mercury provides an accurate reading of temperature but it is not fast and safe as compared to Digital Thermometer.
15 degrees Celsius below 0 is -15 degrees Celsius.
Mercury thermometers can typically measure temperatures up to 500 degrees Celsius (932 degrees Fahrenheit). However, they are not commonly used for measuring high temperatures due to safety concerns associated with the toxicity of mercury.
At 30 degrees Celsius, water, ethanol, and acetone are common examples of liquids. Each of these substances have a melting point below 30 degrees Celsius, allowing them to exist in liquid form at that temperature.
Five degrees below zero on a Celsius scale is -5 degrees Celsius.
16 degrees below freezing, as the freezing point of water is 0 degrees Celsius.
