Front

What is condensation?

Back

Condensation is the process by which water vapor in the air cools and changes into liquid water, forming droplets, such as fog on eyeglasses.

Front

What is density?

Back

Density is the mass of a substance divided by its volume. It determines whether an object will float or sink in a liquid.

Front

What is the process of dissolving?

Back

Dissolving is the process where a solute (like salt) mixes with a solvent (like water) to form a solution.

Front

How can you separate a mixture of salt and sand?

Back

You can separate salt and sand by pouring the mixture through filter paper. The sand will stay on the paper while the salt solution passes through.

Front

What is a solution?

Back

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

Front

What is the relationship between temperature and the solubility of a substance?

Back

Generally, as temperature increases, the solubility of solids in liquids increases, allowing more solute to dissolve.

Front

What is the principle of buoyancy?

Back

Buoyancy is the ability of an object to float in a fluid, which depends on the density of the object compared to the density of the fluid.

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 an example of a physical change?

Back

An example of a physical change is melting ice into water.

Front

What is an example of a chemical change?

Back

An example of a chemical change is rust forming on iron.
