Am mixed raced from and Ghana , my mom is from ghana and my dad is from, but for now am in ghan with my mom , because my dad is now more alive and am working as Hair Dress in Ghana.... WHAT ABOUT YOU
Yes, impurities have important effects on the melting and boiling point of materials.
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.
The boiling point of a substance is the point at which that substance will change between being a gas and a liquid. For example, the boiling point of water is 100oC, so water vapour will change to water at this temperature. The boiling point of Methane is -161oC, so any temperature above this, Methane will be in gas form.
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.
Example: compounds that are thermally decomposed before a supposed melting or boiling point.
what are the differences of boiling and melting? 5 differences wih reasons
what is the melting point and boiling point of substance
Yes, impurities have important effects on the melting and boiling point of materials.
Melting and boiling points are physical properties of materials.

Each pure substance has its own unique melting and boiling point.
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.

The melting point and the boiling point of a substance are physical characteristics for each substance and are unchanged at the same pressure.
and boiling point
The stronger the IMF, the higher the boiling point and the lower the melting point. The weaker the IMF, the lower the boiling point and the higher the melting point.
