Thank you in advance

Material / Substance can be divided into 2 parts namely a single substance and a mixture. A single substance can be an element or a compound. While the mixture can be a homogeneous or heterogeneous mixture.

1. Heat is NOT an example of matter because heat is one of the energies that move because of temperature

2. ability to rust is not physical properties of matter because rusting or also called corrosion is an oxidation event due to the presence of oxygen in air and water(chemical properties)

3. A vapor is the state of gas because water vapor is the result of a change from a liquid to a gas due to an increase in temperature

4. Liquid is characterized by having an indefinite shape, but a definite volume

Indefinite volume and shape means that the sample will change in volume and shape according to the shape of the space occupied by an example such as solid which has a definite shape, definite volume

5. evaporation is a physical change because it does not produce chemical changes (chemical reactions), it only involves changes in its physical form from liquid to gas

Heat is NOT an example of matter.

All of the following are physical properties of matter except the ability to rust.

A vapor is a gaseous state of matter

Liquid is a state of matter is characterized by having an indefinite shape, but a different volume.

Evaporation is a physical change.

Explanation:

The matter is defined as a physical substance that has mass and occupies space. for example. book, stone, etc.

Matter exists in three types of states:

solid: Rigid shape, fixed shape, fixed volume. For example: rock, ice, etc
liquid: Not rigid, No fixed shape, fixed volume. For example: water, blood, etc.
gas: Not rigid, No fixed shape, no fixed volume. For example: water vapors, hydrogen gas, etc.

The matter has two types of physical properties: Extensive properties and intensive properties.
Properties that are dependent upon the shape and size of the matter are extensive properties. For example mass, volume, length.etc
Properties that are independent of the shape and size of the matter are intensive properties. For example density, melting point, color, etc.
A physical change is defined as a change in form of a substance in which no change in the chemical composition of the substance occurs. for example, melting, boiling, evaporation, etc.
A chemical change is defined as a change in form of a substance in which a change in the chemical composition of the substance occurs. for example, rusting, rotting, combustion, etc.

So, from this, we can conclude that the:

Heat is NOT an example of matter.

All of the following are physical properties of matter except the ability to rust.

A vapor is a gaseous state of matter.

Liquid is a state of matter is characterized by having an indefinite shape, but a different volume.

Evaporation is a physical change. Other are examples of chemical change.
