The freezing point of helium is -272 degrees Celsius The original temperature of a sample of helium is 3 degrees Celsius how much must the temperature change to ensure that helium freezes?
275 degrees
Is it true that the temperature must drop lower than 0 Celsius for water to freeze when a solute is dissolved in the water?
Yes if something is dissolved in the water then it is no longer pure water and the freezing point will change
What temperature does a phase change begin?
It will start to melt if the temperature rises above 0 degrees Celsius or 32 degrees FahrenheitOfficially, the melting temperature of ice is zero degrees Celsius (or 32F). The freezing temperature does vary dependent on the electrolytes added to the water solution. For example, ocean water (salt water), freezes at ~-18 degrees Celsius (or 0F). Various solutions at different concentration of solute offer various degrees of melting/freezing. At 0 degrees Celsius.
Change 46 degrees Fahrenheit to Celsius?
46 degrees Fahrenheit = 7.78 degrees Celsius
At what degrees celsius does a liquid turn to a solid?
The freezing point of water is when it will change from a liquid state to a solid state; the freezing point of water is 0 C.
How does water change into a solid?
The process of freezing. The freezing point of water is zero degrees Celsius, or 32 degrees Fahrenheit.
What is water at 20 degree Celsius?
It just remains as water. The freezing point of water is 0 degrees Celsius, while the freezing point is 100 degrees Celsius. Therefore at 20 degrees Celsius, there is no change in state and it just remains as water.
How can liquids change into solids?
By freezing the liquid to 32 degrees Fahrenheit, or 0 degrees Celsius.
What is the boiling point of fresh water?
There is no specific boiling point of rain water. It may have dissolved some atmospheric gases, which can change its boiling or freezing point. The boiling and freezing point of rain water depends on the content of the dissolved gases.
What temperature does water freeze in Celsius?
Zero degrees Celsius. The Celsius temperature scale was defined with zero as the freezing point of water, and 100 as the boiling point of water. (That's for pure fresh water at sea-level atmospheric pressure. Adding impurities to the water will change the freezing and boiling temperatures, and different air pressures will change the boiling temperature of water.)
The freezing point of helium is -272 degrees Celsius The original temperature of a sample of helium is 3 degrees Celsius how much must the temperature change to ensure that helium freezes?
275 degrees

Yes if something is dissolved in the water then it is no longer pure water and the freezing point will change
Are celsius and Fahrenheit degrees the same size?
No. Celsius "degrees" are larger than Fahrenheit "degrees", and so represent a larger change in temperature. One Celsius "degree" is equal to 1.8 Fahrenheit "degrees". The Fahrenheit scale has 180 divisions (degrees) between 32° and 212° - the freezing and boiling points of water. The Celsius scale has only 100 divisions (degrees) between 0° and 100° - the freezing and boiling points of water. So the Celsius degrees are "larger" degrees, and a change in temperature in Celsius will be 1.8 times as large on the Fahrenheit scale. That is where the 5/9 and 9/5 fractions come in on the conversion formulas. (see related question)
Which is greater an increase in temperature of 1 celsius degree or an increase of 1 Fahrenheit degree?
Both scales use "degrees" but they are not the same size.Celsius degrees are larger intervals, so a change in "Celsius degrees" is larger than an identical numerical change in "Fahrenheit degrees."A change of 1 Celsius "degree" is the same change as 1.8 Fahrenheit "degrees", as is seen in the difference between the freezing and boiling point of water. 100 Celsius degrees (0° to 100°C) is the same temperature change as 180 Fahrenheit degrees (32° to 212°F).
What is the tempertaure change if it was 22 degrees celsius and dropped to -6 degrees celsius?
28
What is the freezing point of water for celsius and Fahrenheit?
The freezing temperature of water doesn't change. It just has different names. If you're speaking in Celsius, it's called zero. If you're speaking in Fahrenheit, it's called 32 degrees.
What temperature does a phase change begin?
