Back

A solution is a mixture where one substance (solute) is dissolved in another (solvent), such as salt in water.

Front

How can you separate a mixture of salt and water?

Back

Front

What happens when oil and water are mixed?

Back

Oil floats on water because it is less dense than water.

Front

What tool is used to measure mass?

Back

A triple beam balance is used to measure mass.

Front

How do scientists determine if an object is denser than water?

Back

Scientists determine if an object is denser than water by placing it in water and observing if it sinks or floats.

Front

What is density?

Back

Density is the mass of an object divided by its volume, indicating how much matter is packed into a given space.

Front

What is the boiling point of water?

Back

The boiling point of water is 100 degrees Celsius (212 degrees Fahrenheit) at sea level.

Front

What is evaporation?

Back

Evaporation is the process where liquid turns into vapor, often due to heat.
