Matter and Energy Quiz

What is the characteristic of matter that defines its resistance to a change in its state of motion?

• acceleration

• inertia

• gravity

• speed

Answer explanation

Inertia is the property of matter that describes its resistance to change in motion.

What are the three states of matter?

• solid, liquid, and plasma

• round, square, and triangle

• hot, cold, and warm

• solid, liquid, and gas

Answer explanation

The three states of matter are solid, liquid, and gas. These states are determined by the arrangement and movement of particles.

Which state of matter keeps its shape and volume?

• gas

• liquid

• solid

Answer explanation

A solid is a state of matter that has a definite shape and volume. In this case, the correct choice is solid.

Which state of matter keeps its volume but takes the shape of its container?

• Liquid

• Gas

• Solid

Answer explanation

The state of matter that has a definite volume but takes the shape of its container is liquid. Liquids can flow and fill the shape of their container while maintaining a fixed volume.

Which state of matter has neither a definite shape nor volume?

• solid

• liquid

• gas

Answer explanation

Gas is a state of matter that has neither a definite shape nor volume. It is composed of particles that are widely spaced and move freely. This makes gas highly compressible and able to fill any container it is placed in.

What are some examples of energy sources?

• Solar, wind, hydro, fossil fuels, nuclear

• Plastic, glass, metal

• Geothermal, tidal, biomass

• Coal, natural gas, wood

Answer explanation

Examples of energy sources include solar, wind, hydro, fossil fuels, and nuclear. These sources provide power for various applications and are essential for meeting our energy needs.
