Exploring Physical Properties of Matter

This lesson explores the physical properties of matter, distinguishing between size-dependent and size-independent properties. It covers mass, volume, state of matter, density, conductivity, solubility, and magnetism. The lesson also introduces techniques for separating mixtures, such as chromatography, crystallization, distillation, filtration, and sublimation.

What is a physical property of matter?

• A characteristic that can be observed or measured without changing the identity of the matter

• A property that only applies to liquids

• A characteristic that involves a chemical reaction

• A property that changes the matter's identity

How is mass different from weight?

• Mass is only relevant in space

• Mass is the amount of matter in an object, while weight is the force on an object due to gravity

• Mass is the force on an object due to gravity, while weight is the amount of matter in an object

• Mass and weight are the same

What unit might you use to measure volume?

• Milliliters or cubic centimeters

• Newtons

• Meters

• Kilograms

Which of the following is a size-independent property?

• Weight

• Mass

• Density

• Volume

What is the melting point?

• The temperature at which a liquid turns into a gas

• The temperature at which a solid turns into a liquid

• The temperature at which a liquid turns into a solid

• The temperature at which a gas turns into a solid

What happens to particles in a solid when thermal energy is added?

• They become a gas immediately

• They start to move more and become a liquid

• They become more tightly packed

• They lose energy and stop moving

What is chromatography based on?

• Density and travel rate

• Magnetism

• Solubility

• Boiling points

What is the principle behind crystallization?

• Solubility of a substance

• Density

• Boiling points

• Magnetism

What is distillation used for?

• Separating mixtures based on magnetism

• Separating mixtures based on solubility

• Separating mixtures based on boiling points

• Separating mixtures based on density

What is sublimation?

• A process where a liquid turns into a gas

• A process where a gas turns into a solid

• A process where a solid turns into a liquid

• A process where a solid turns directly into a gas
