Science Flashcard (LIA 2)

Front

What are the common weather conditions in the southwestern United States during summer?

Back

High temperature, low rainfall.

Front

What factors can affect how fast a material dissolves in water?

Back

Temperature, surface area, stirring, and the type of solute.

Front

What is evaporation?

Back

Evaporation is the process by which water changes from a liquid to a gas, often due to heat.

Front

What should you do if two experiments yield different results?

Back

Reject both sets of results and perform the experiment again.

Front

What happens when a balloon is rubbed against a sweater?

Back

The balloon becomes negatively charged due to the transfer of electrons.

Front

What is the role of heat in the evaporation process?

Back

Heat increases the energy of water molecules, allowing them to escape into the air as gas.

Front

What is a solute?

Back

A solute is a substance that is dissolved in a solution.

Front

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.

Front

What is the scientific method?

Back

The scientific method is a systematic process for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge.

Front

What is the importance of repeating experiments in science?

Back

Repeating experiments helps verify results and ensures accuracy.
