Magnesium sulfate doesn't melt; at high temperature MgSO4 is thermally decomposed.
The scientific term for when ice turns to water is "melting." It is a phase change from solid to liquid that occurs when the temperature of the ice rises above its melting point.
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
The melting point of silicon is 1414 degrees Celsius (2577 degrees Fahrenheit). Silicon is a crystalline solid at room temperature but transitions to a liquid state above its melting point.
The inner core of the Earth has a temperature higher than its melting point. Despite being made of solid iron and nickel, the immense pressure at the center of the Earth keeps it in a solid state even at temperatures above its melting point.
H2O is water. The melting point of water is 0oC or 32oF

-- 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
Yes: FAR above.
is the temperature if the stiffer mantle above or below its melting point
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 if the stiffer mantle above or below its melting point
Iodine melting point is above room temperature because its vapor pressure is less than one atmosphere.
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.
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.
The melting point is the temperature which a material, element or mixture, changes from the solid to a liquid. Therefore, all liquids become solids above the melting point.
is the temperature if the stiffer mantle above or below its melting point
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.
