How is the melting point of asolid and boiling point of a liquidaffected when impurities are added to the substances?
Adding impurities lowers the melting point and raises the boiling point.
Calcium melting point and boiling point?
The melting point of Calcium is 839℃ and the boiling point is 1484℃.
Explain why the boiling point and the melting point can be used to help identify substances?
100 degrees mate. 100 degrees Celsius is the boiling point for pure water at 1atm or sea level. The boiling point is useful in identifying chemical compounds. Chemical compounds have different boiling points that are specific to it' s chemical composition. If you know what the boiling point or melting point is you can also tell if your compound is pure, as any impurities will change these.
What is nitrogen melting and boiling point?
Melting point −209.86°C; boiling point −195.8°C
What is the boiling melting and freezing point?
A boiling point is a point on the temperature scale at which a substance begins to boil. A melting point is a point on the temperature scale at which a substance freezes. Melting and boiling points are unique to different types of elements.
Do elements compounds and mixtures have fix melting and boiling point?
Yes, elements have fixed melting points; but some exceptions are with the elements having allotropes (as carbon, sulfur, phosphorous, etc.) - each allotrope has a specific melting point.
How is the melting point of asolid and boiling point of a liquidaffected when impurities are added to the substances?
Adding impurities lowers the melting point and raises the boiling point.
Why are the temperatures of the melting point of ice boiling point of water called fixed point in calibrating the thermometer?
it is because they were consistent at melting and boiling point
What is mean by melting and boiling point?
Melting point & boiling point means the temp that things melt & boil. Water's freezing & melting point is 32 degrees Fahrenheit or 0 degrees Celsius. The boiling point of water is 100 degrees Celsius or 212 degrees Fahrenheit. Different liquids or substances have different melting, freezing, and boiling points.
What is lower fixed point?
upper fixed point is a temperature of stem from water boiling and standards atmospheric pressure lower fixed point is the temperature of pure melting ice.
How can iodine have a melting point?
All substances have melting points and boiling points. A melting point is merely the temperarture at which it changes from a solid to liquid and vice versa. The boiling point of a substance would be the temperature at which it changes from liquid to gas and vice versa.
