Front

What are the three states of matter?

Back

The three states of matter are solid, liquid, and gas.

Front

What is a solid?

Back

A solid is a state of matter that has a definite shape and volume, with molecules that are tightly packed together.

Front

What is a liquid?

Back

A liquid is a state of matter that has a definite volume but takes the shape of its container, with molecules that are close together but can move past one another.

Front

What is a gas?

Back

A gas is a state of matter that has no definite shape or volume, with molecules that are far apart and move freely.

Front

What tool do we use to measure mass?

Back

We use a triple beam balance or a digital scale to measure mass.

Front

What are physical properties?

Back

Physical properties are characteristics of a substance that can be observed or measured without changing the substance's identity, such as color, texture, and density.

Front

What is solubility?

Back

Solubility is the ability of a substance to dissolve in another substance, usually a liquid.

Front

What is conductivity?

Back

Conductivity is the ability of a material to conduct electricity or heat.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.
