Magnetism, solubility, and malleability are physical properties of matter. What makes these properties different from chemical properties?
Physical properties relate to elements rather than compounds.
Physical properties appear only after a chemical change occurs.
Physical properties can be observed without attempting to change the identity of the substance.
Physical properties describe elements in the solid state rather than in the liquid or gas state.
A child is upset because his ice cream is melting. He thinks he now has less dessert. Which of the following explanations correctly states why the child is incorrect?
He actually has more, not less, ice cream
No mass is lost during a change of state
The mass will increase if he freezes the melted ice cream.
Mass is lost only during certain changes of state, such as freezing.
Which of the following is a way in which elements and compounds are similar?
Elements and compounds are both pure substances.
Elements and compounds are both listed on the periodic table.
Elements and compounds are both made up of different kinds of atoms.
Elements and compounds can both be broken down by physical changes.

all of the particles
In which state(s) of matter are particles constantly moving?
gases only
liquids only
gases and liquids only

Which of these statements best describes physical properties?
Physical properties behave identically for all matter under the same conditions.
Physical properties can be observed without changing the identity of a substance.
Physical properties are observed by seeing how a substance reacts with other substances.
Physical properties cause atoms and molecules to change structure when substances are mixed.
What happens at the melting point of a substance?
The substance begins to turn from a solid into a gas.
