Properties of Matter and Force Flashcard

Front

What are the properties of matter?

Back

Properties of matter include physical properties (like color, density, and melting point) and chemical properties (like reactivity and flammability).

What is density?

Back

Density is the mass of an object divided by its volume, often expressed in grams per cubic centimeter (g/cm³).

What is thermal conductivity?

Back

Thermal conductivity is the ability of a material to conduct heat. Materials that conduct heat well are called conductors.

Front

What is friction?

Back

Friction is the resistance that one surface or object encounters when moving over another. It can affect the motion of objects.

What happens to sugar when it dissolves in water?

Back

When sugar dissolves in water, it breaks down into smaller particles and spreads throughout the water, but it retains its sweetness.

Front

What is a soluble substance?

Back

A soluble substance is one that can dissolve in a solvent, such as sugar in water.

Front

What is an insulator?

Back

An insulator is a material that does not conduct heat or electricity well, such as rubber or glass.

Front

What is the effect of temperature on the solubility of substances?

Back

Generally, increasing the temperature increases the solubility of solids in liquids.

Front

What is a magnet?

Back

A magnet is an object that produces a magnetic field, which can attract or repel certain materials, like iron.

What is the difference between a physical change and a chemical change?

Back

A physical change alters the form of a substance but not its chemical composition, while a chemical change results in the formation of new substances.
