Front

What is buoyancy?

Back

Buoyancy is the ability of an object to float in a fluid (liquid or gas) due to the upward force exerted by the fluid.

Front

What is density?

Back

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

Front

What happens to the density of an object if its mass increases but its volume stays the same?

Back

If the mass increases while the volume remains the same, the density of the object increases.

Front

What is the difference between solids, liquids, and gases?

Back

Solids have a definite shape and volume, liquids have a definite volume but take the shape of their container, and gases have no definite shape or volume.

Front

What is a conductor?

Back

A conductor is a material that allows heat or electricity to pass through it easily.

Front

What is an insulator?

Back

An insulator is a material that does not allow heat or electricity to pass through it easily.

Front

What is the particle arrangement in solids?

Back

In solids, particles are tightly packed together in a fixed arrangement.

Front

What is the particle arrangement in gases?

Back

In gases, particles are far apart and move freely, filling the entire container.

Front

What is the role of temperature in the state of matter?

Back

Temperature affects the energy of particles; higher temperatures can cause solids to melt into liquids and liquids to evaporate into gases.

Front

What is a molecule?

Back

A molecule is a group of two or more atoms bonded together.
