What does -12 Celsius mean?
It means the temperature is 12 degrees Celsius (or 12o Centigrade, or 12 Kelvin) below the freezing point of pure water at normal pressure.
Can centigrade and Fahrenheit be negative?
Yes, they can. Centigrade (Celsius) can go as low as -273.15 degrees C. The same temperature on the Fahrenheit scale is -459.67 degrees -- both indicate absolute zero (0K). A notable difference caused by having "degrees" of two different sizes and definitions is that negative temperatures on Celsius indicate "below the freezing point of water" (0 degrees C), while below freezing on the Fahrenheit scale includes positive values from 31 down to 0, the freezing point being 32 degrees F.
What is sub zero?
Sub-zero is anything that is less than zero. That means that-1 degree, -2 degrees, -3 degrees, etc. are all 'sub-zero'. To be complete, you also have to specify whether you are talking centigrade or Fahrenheit. When centigrade, it just means the same as below freezing (0 degrees centigrade). When Fahrenheit, sub zero is starting to be seriously cold since freezing is +32 degrees Fahrenheit.
What is the change in temperature between 15 degrees below zero and 8 degrees below zero?
A rise of 7°
What is the corresponding number for the temperature of -7 degrees below zero?
-7 degrees below zero is 7 degrees above zero.-7 degrees below zero is 7 degrees above zero.-7 degrees below zero is 7 degrees above zero.-7 degrees below zero is 7 degrees above zero.
How low does the temperature have to be snow?
Snow is made from Ice crystals. Thus for snow to form and precipitate, the ambient / air temperature must be below 0 degrees Centigrade.
When do Celsius and Fahrenheit have same temperature?
Celsius and Fahrenheit have the same temperature at -40 degrees, as it is the point where the two temperature scales intersect. Below -40 degrees, the Celsius temperature is lower than its Fahrenheit equivalent.
What temperature is sub zero?
Sub-zero is anything that is less than zero. That means that-1 degree, -2 degrees, -3 degrees, etc. are all 'sub-zero'. To be complete, you also have to specify whether you are talking centigrade or Fahrenheit. When centigrade, it just means the same as below freezing (0 degrees centigrade). When Fahrenheit, sub zero is starting to be seriously cold since freezing is +32 degrees Fahrenheit.
Why is there fog in the winter?
Condensate is the correct term, Human breath will condense ( for a water vapor) when the outside temperature ( static, not wind chill) is at or below 50 degrees Fahrenheit or l0 degrees centigrade. This is some distance between the freezing point of water, 32 degrees F, or 0 Centigrade. If you can see your breath it is fifty degrees or below this mark. Handy rule of thumb.
At what degrees does water freeze?
0 degrees centigrade 32 degrees Fahrenheit
Why do you need the freezer turned on to make Ice?
Ice will only form from water once water is cooled to below 0 degrees Centigrade. A freezer requires energy (ie it needs to be turned on) in order to pump heat out of the freezing compartment to lower the temperature in this compartment to below 0 degrees Centigrade. If the freezer is not turned on the temperature in the freezing compartment will be that of the room in which the freezer is kept.
Is water a solid liquid or gas at 0 degrees c?
When water reaches 0 degrees centigrade (32 degrees Fahrenheit) it begins to change to ice, a solid. This process of changing to ice can be very slow with the temperature changing throughout the day, water also doesn't instantly change to ice when the temperature hits 0 degrees centigrade, it takes time. The amount of time it takes varies on how far the temperature goes below 0 degrees centigrade. We also call 0 degrees centigrade (32 degrees Fahrenheit) the freezing point. To answer your question water can be either a solid or a liquid at the freezing point depending on if it's already ice, or it was water before.
Why the boiling point of liquid hydrogen chloride gas is negative and what does negative sign mean?
The boiling point of liquid hydrogen chloride gas is negative because it boils at a temperature below 0°C due to its low boiling point and high vapor pressure. The negative sign indicates that the substance boils below its freezing point, making it a gas at room temperature and pressure.
What is the temperature at 10000 ft below sea level?
At 10,000 feet below sea level in the ocean, the temperature hovers at about 4 degrees centigrade. On solid ground, at 10,000 feet down, the rock is hot enough to boil water.
How do you freeze a water?
Freeze a water? I'll assume you mean "How do you freeze water?" I'm not sure if this is a serious question or not but, lower it's temperature below 32 degrees farenheight or 0 degrees centigrade.
Can water exist as H2O?
H2O is defined as - a binary compound that occurs at room temperature as a clear colorless odorless tasteless liquid; freezes into ice below 0 degrees centigrade and boils above 100 degrees centigrade; widely used as a solvent - does that sound like water to you .
What is -50 degrees centigrade?
-50 degrees Celsius is a very cold temperature, equivalent to -58 degrees Fahrenheit. It is well below freezing and considered dangerously cold for human exposure without adequate protection.
