Physical properties can be used to compare and classify substances. Which statement is correct about a physical property?

• A physical property can be observed or measured without changing the identity of the substance.
• A physical property is difficult to observe and even more difficult to measure.
• A physical property describes a substance’s ability to be involved in a chemical reaction.
• A physical property is based on a substance’s ability to change into a new substance.

Thomas performed an experiment to measure the temperature of water as he heated it on a hotplate. At the end of his experiment, he plotted the results as shown in the graph below. Which of the following physical properties of water did Thomas measure?

• densities and physical states of matter
• melting point and boiling point
• volume and thermal conductivity
• solubility and electrical conductivity

The state of matter is an example of a physical property. Why is the state of matter considered a physical property even though a substance may change between a solid, liquid, and gas?

• The state of matter depends on the amount of substance present.
• The chemical nature of the substance does not change.
• Solids, liquids, and gases have different chemical compositions from one another.
• The property can be easily observed.

Ductility is the ability of a substance to be stretched into a wire. For example, copper is often used for electrical wiring because it is highly ductile. Why is ductility considered a physical property?

• The substance being stretched into a wire develops a lower melting point.
• The substance being stretched into a wire retains its identity.
• The substance being stretched into a wire increases its density.
• The substance being stretched into a wire changes its identity.

Physical properties are used to classify and compare substances. Physical properties can include density, thermal conductivity, electrical conductivity, solubility, magnetism, melting point, and boiling point. Which statement is correct about all of these physical properties listed above?

• They involve a change in the identity of matter.
• They are independent of the amount of the sample present.
• They can be measured only after a change in identity.
• They involve the production of new substances.
