What else can I help you with?
Is a melting points a physical or chemical change?
Melting point is a physical property, not a change.
Is water at room temperature a physical property?
Yes it is. Properties like Boiling and melting points are physical properties.
Is the state of matter considered a physical property?
The state of matter of a element or compound is linked to its melting and boiling points which are both physical properties. Also if the element/compound is a solid you could say physical properties on the type of structure it would form
What is difference between extensive physical property and intensive physical property?
Anintensive property is a property of matter that is independent of the quantity of the substance. Density, boiling and melting points, and specific gravity are all intensive properties.An extensive property depends on the quantity of a substance. Mass and volume are extensive properties.
What physical property is most useful in identifying a unknown substance?
The most useful physical property for identifying an unknown substance is its melting point. This property is characteristic of a substance and can help distinguish it from others, as pure substances have specific melting points. Additionally, comparing the melting point of the unknown with known values can provide a quick and reliable identification method. Other useful physical properties may include boiling point, density, and solubility, but melting point is often the most definitive.
What is physical propety?
Physical property is a property that a substance has which can be measured. For instance, some properties are melting points or boiling points.
Is a melting points a physical or chemical change?
Melting point is a physical property, not a change.
Is crystalline solid a physical property or chemical property?
Physical as melting and boiling points are physical properties.
Is water at room temperature a physical property?
Yes it is. Properties like Boiling and melting points are physical properties.

Anintensive property is a property of matter that is independent of the quantity of the substance. Density, boiling and melting points, and specific gravity are all intensive properties.An extensive property depends on the quantity of a substance. Mass and volume are extensive properties.
What is a property of sodium chloride that is not a property of sodium or chloride?
The melting point of NaCl is very different from the melting points of Na or Cl.
What physical property is most useful in identifying a unknown substance?

What temp is melting pt?
The melting point is the temperature at which a solid transitions into a liquid. This temperature varies depending on the substance; for example, water has a melting point of 0°C (32°F) at standard atmospheric pressure, while metals like iron have much higher melting points, around 1,538°C (2,800°F). The melting point is a key physical property used to identify and characterize materials.
What is the physical property of a metal?
Physical properties are that they are hard, dense, shiny, malleable (can be bent), ductile (can be pulled into wires), a good conductor of heat and have high melting points meaning that they are solid at room temperature
What two uses do chemist put the melting points of substances?
- a substance can be identified after the melting point because it is a specific physical characteristic- melting points knowledge is necessary for technology
