Science Category 1 Review

Front

What is a physical property of matter?

Back

A characteristic of a substance that can be observed or measured without changing its identity, such as color, density, or melting point.

Front

What does it mean for a material to be magnetic?

Back

A material that is attracted to magnets or can be magnetized, such as iron.

Front

What is the difference between conductors and insulators?

Back

Conductors allow electricity to flow through them easily (e.g., metals), while insulators do not (e.g., rubber).

Front

What is density?

Back

Density is the mass of a substance divided by its volume, often determining whether an object will float or sink in a fluid.

Front

What happens when a substance dissolves in water?

Back

The substance breaks down into smaller particles and spreads evenly throughout the water, forming a solution.

Front

What is the process of separating materials based on their physical properties?

Back

It involves using techniques like filtration, evaporation, or magnetic separation to isolate different components.

Front

What is a solution?

Back

A homogeneous mixture where one substance (solute) is dissolved in another (solvent), such as sugar in water.

Front

What is the role of temperature in dissolving substances?

Back

Higher temperatures generally increase the solubility of solids in liquids, allowing them to dissolve faster.

Front

What is the significance of the term 'less dense than water'?

Back

Objects that are less dense than water will float, while those that are more dense will sink.

Front

What is filtration?

Back

A method used to separate solids from liquids by passing the mixture through a filter that allows only the liquid to pass.
