What is a melting point of h20?
H2O is water. The melting point of water is 0oC or 32oF
In what state of matter is calcium nitrate at room temperature?
Melting point 561 °C (anhydrous) 42.7 °C (tetrahydrate)Boiling point decomposes (anhydrous) 132 °C (tetrahydrate) Calcium nitrate has the above data from the relevant wikipedia page. This means that at room temp (250C), it is solid
How can the mass of a pile of snow decrease on a sunny day when the air temperature does not rise above zero degrees celsius?
When the sunlight strikes the snow, the surface of the snow is heated above the air temperature and some melting and evaporation occur.
What is the temperature at which ice starts melting?
Freezing: 0 Celsius or 32 Fahrenheit, unless the sun is shining on it and the temperature is just below freezing.
Why caesium is liquid at nearly room temperature?
Why not? Or, in other words, there's not really a "why" to explain here; it's an extension of a well-established trend (unlike mercury, which is a liquid at room temperature while all the metals around it are solid and there's no such trend that would predict its dramatically lower melting point). The trend for alkali metals is that they have lower melting points as you move down the table. By the time you get to caesium, it's only a little above room temperature, and the theoretical melting point for francium is even lower than that (but still slightly above room temperature).
Is Magnesium melting point above room temperature?
Magnesium sulfate doesn't melt; at high temperature MgSO4 is thermally decomposed.
What are 5 liquids that do not have water?
-- pure alcohol at room temperature -- mercury at room temperature -- oxygen below its boiling temperature -- iron above its melting temperature -- nitrogen below its boiling temperature -- salt above its melting temperature -- gold above its melting temperature -- any other element or compound that is not H2O, above its melting temperature and below its boiling temperature
When a material is melting the temperature?
When a material is melting, the temperature is likely to be increasing. That or the temperature is just above the material's melting/freezing point.
Is the temperature of the stiffer mantle above of below its melting point?
is the temperature if the stiffer mantle above or below its melting point
Is magnesium sulphate melting point above 50 degrees Celsius?
Yes: FAR above.
Is the stiffer mantle above or below the melting point?
is the temperature if the stiffer mantle above or below its melting point
Why Iodine melting point is above room temperature?
Iodine melting point is above room temperature because its vapor pressure is less than one atmosphere.
How can you determine if a substances is a solid at room temperature?
Check the melting point of the substance. If the melting point is below room temperature, then the substance is liquid and if the melting point is above room temperature then it is solid.
Is the temperature of the stiffer mantle above or below its mantle point?
is the temperature if the stiffer mantle above or below its melting point
How can you use boiling points and melting points to determine a solid liquid or gas that an element would be in at a certain temperature?
If the temperature is below the melting point then the element is a solid.If the temperature is above the melting point but below the boiling point, then the element is a liquid.If the temperature is above the boiling point, then the element is a gas.
What is the melting point of Magnesium oxide?
The melting point of magnesium chloride depends upon the rate at which the heat is applied. With slow heating, the material will decompose above 300oC. With rapid heating, the melting point is about 714oC.
What do boiling point and melting point have to do with the phase of matter of an element at room temperature?
The state of matter of a substance at room temperature depends on whether the melting and boiling points are above or below room temperature. At room temperature:A substance is solid if both the melting and boiling points are above room temperature.A substance is liquid if the melting point is below room temperature but the boiling point is above room temperature.A substance is a gas if both the melting point and boiling point are below room temperature.
