The melting and boiling points of a material are physical properties of that material.
Melting is a solid becoming a liquid, and boiling is a liquid becoming a gas. These are changes between the three different phases a substance can be in (solid, liquid, and gas*). Both of these changes can occur through the application of varying amounts of heat** . All substances can go through these stages. When a substance changes stages, they remain the same substance, so the change is a physical change.
*a fourth, controversial stage is plasma, which is an electrically charged substance.
**A liquid can also become a gas by extreme low pressure.

Are melting and boiling point physical properties of a substance?
Yes, melting and boiling points are physical properties of a substance. They represent specific temperatures at which a substance transitions from one phase to another - solid to liquid for melting point, and liquid to gas for boiling point.
What are three physical properties of lava?
melting point boiling point density
What physical properties are intensive?
The three intensive physical properties are density, boiling point and melting point.
What is the simple physical test to show that a sample of water is pure?
A scientific test you do on water similar to a chemical test
Does melting and boiling cause physical changes?
Melting and boiling are physical changes.
Boiling point melting and density are some of an elements nonreactive physicalor chemical properties?
Boiling point, melting point, and density are all physical properties of an element. They determine the state of the element.
What are 3 intensive physical properties?
Density, melting point, and boiling point are three examples of intensive physical properties. These properties do not depend on the amount of substance present and are useful for identifying and characterizing materials.
What are you physical properties that can help you identify a substance?
The traditional ones are melting point and boiling point.
What physical properties does water have in it?
Some physical properties include density, boiling point, and melting point. At 4 oC, the density of water is 1.00g/cm3. At sea level, water's boiling point is 100 oC and its melting point is 0 oC.
What is true of a melting point and a boiling point?
The melting point is the temperature at which a solid turns into a liquid, while the boiling point is the temperature at which a liquid turns into a gas. Both melting and boiling points are physical properties that are specific to each substance and can be used to identify and characterize materials.
How can you tell that the melting of ice cube is a physical change?
You could test the resulting liquid by determining its boiling point and melting point. If they are the same as the boiling and melting points for water, then it is probably water and a physical change rather than a chemical change has occurred.
Is the boiling point of a substance a physicsl property?
No, the boiling point is a physical property because the compound or substance is not changing chemically (only physically from a liquid to a gas). The boiling point is considered the temperature at which the vapor pressure of the liquid equals the atmospheric pressure surrounding the liquid. All of these are physical properties, making the boiling point a physical property too.
