Which temperature scale has 100 degrees between freezing and boiling?

The Celsius temperature scale has 100 degrees between freezing and boiling.


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.


Why can boiling points and freezing points be used to identify substance?

It's because substances have different boiling point and freezing point. By finding the exact boiling point and freezing point, you can identify a substance. Keep in mind that a material's melting point is the same as its freezing point. These are just different terms for the same thing, it just depends on whether energy is being removed from a substance (freezing) or if energy is being added to a substance (melting). The same thing also applies to the boiling/condensation point.


What is the boiling temperature in degrees Celsius?

Different substances have different boiling temperatures.

Why do chemicals separate out in a particular order?

In fractional distillation, the substances in a mixture are heated to their boiling points. Different substances have different boiling points, so will be separated at different times. The answer to your question is simply because they have different boiling points.


What are the freezing and boiling points on the kelvin Fahrenheit and Celsius scales?

We'll assume you're asking about water, since different substances have different freezing and boiling points. Under normal atmospheric conditions, water freezes at 0 C, 32 F and 273.15 K and boils at 100 C, 212 F and 373.15 K.


Why do we do disillation?

To separate substances (that have different boiling points).


What Are Two Physical Properties That can vary even when the substances with these properties does not change?

Color/smell or freezing/ boiling point.


How would you use the boiling point of a substance to identify a specific substances?

Because each compound has a specific boiling point (with some exceptions) comparing exactly determined boiling points we can identify compounds.


How do celsius and Fahrenheit express freezing and boiling points of water differently?

Not sure that they are different necessarily, just different scales. The freezing and boiling points of water are the same no matter which scale is used. In degrees, the Celsius scale measures the temp at 0 degrees for freezing and 100 degrees for boiling. Farenheit scales measures the freezing point at 32 degrees and the boiling point at 212 degrees.
