Physical Properties of Matter

What is a solution?

• A heterogeneous mixture of two or more substances.

• A homogeneous mixture where one substance is dissolved in another.

• A pure substance with a fixed composition.

• A mixture that can be separated by physical means.

What happens to the physical properties of a substance when it is combined with other substances?

• They remain unchanged.

• They can change, resulting in a solution.

• They become more solid.

• They evaporate completely.

What is the ability of a substance to dissolve in water called?

• Solubility

• Insolubility

What is a thermal insulator?

• A material that allows heat to flow easily through it.

• A material that does not allow heat to flow through it.

• A material that absorbs heat quickly.

• A material that reflects heat away from its surface.

What is matter?

• Anything that has mass and takes up space.

• A substance that can be seen but not touched.

• An object that exists only in theory.

• A form of energy that cannot be measured.

What is density?

• Density is the mass of a substance divided by its volume.

• Density is the weight of an object regardless of its size.

• Density is the volume of a substance divided by its mass.

• Density is the measure of how much space an object occupies.

Does your mass change if you go to another planet?

• True. Your mass changes based on the planet's gravity.

• False. Your mass remains the same regardless of location.

• It depends on the planet's atmosphere.

• Yes, your mass increases on larger planets.

What is a mixture?

• A combination of two or more substances where each retains its own properties.

• A single substance that cannot be separated into its components.

• A solution where one substance completely dissolves in another.

• A homogeneous mixture of two or more elements that are chemically bonded.

What is the freezing point?

• The temperature at which a liquid turns into a solid.

• The temperature at which a solid turns into a gas.

• The temperature at which a liquid becomes a gas.

• The temperature at which a solid becomes a liquid.

What is an example of a physical property?
