3 degrees celsius below zero is written as?
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?
Why don't thermometers read down to -300 degrees Celsius?
Well, first of all, absolute zero, the point at which there is no thermal energy is at -273 degrees Celsius, so nothing could ever get to -300 C. Also, the mercury in the thermometer would freeze long before absolute zero, and it is unlikely that a standard thermometer would ever be used below its minimum measurement. If temperature measurement was needed below the minimum measurement of a thermometer, specialized scientific thermometers are available.
How many degrees below freezing is minus 16 degrees celsius?
-16 degrees Celsius is 28.8 degrees below freezing (3.2 degrees Fahrenheit).
What is 10 degrees below in Celsius in Fahrenheit?
-10 degrees Celsius = 14 degrees Fahrenheit.
What degrees are below freezing?
32 Degrees F and below = For Fahrenheit Below 0 degrees in Celsius
3 degrees celsius below zero is written as?
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?
When is mercury a solid?
When very cold, at or below -39 degrees Celsius (-38 degrees Fahrenheit) mercury is a solid.

Why wouldn't you take a mercury in glass thermometer with you to south pole?
If I only had those 2 choices... I would use ALCOHOL since Mercury freezes at -38.72° Celsius. The North Pole can get down below -50° Celsius. Ethanol (alcohol) freezes at -114 ° Celsius Methanol (alcohol) freezes at -97.8° Celsius
What are the relative advantages and disadvantages of thermocouple and thermometer and mercury thermometer?
Thermocouples can measure a wide range of temperatures however accuracy is a common limitation. Thermometers give consistent results however they may become decalibrated easily. Mercury thermometers are extremely accurate but they cannot be used at temperatures below negative 38 degrees Celsius.
Why is in water used in thermometers?
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.
How do you change Mercury powder into liquid Mercury?
You will need to cool it below -39 degrees Celsius (-38.83, plus remove the heat of fusion).
What is the highest temperature a mercury thermometer can measure?
The planet Mercury turns so slowly that any given location experiences 88 days in the blistering light of the Sun. Temperatures on the daylight side can reach 700 K, which is 427°C or 801 °F.

Is 30 degrees Fahrenheit below zero?
The number 30 is above zero. Is this a trick question ? At the same temperature, a Celsius thermometer will read -1.
How many degrees below freezing is minus 16 degrees celsius?
-16 degrees Celsius is 28.8 degrees below freezing (3.2 degrees Fahrenheit).
What is 10 degrees below in Celsius in Fahrenheit?
-10 degrees Celsius = 14 degrees Fahrenheit.
