States of Matter

Question 1

What is Matter?

Answer 1

Matter is anything that occupies space and has mass

Question 2

What are the three common states of Matter?

Answer 2

Solid
Liquid
Gas

Question 3

In which states of matter does sound travel fastest?

Answer 3

Solids because the molecules of a solid are closer together and therefore, can transmit the vibrations (energy) faster.

Question 4

In which state of matter does light travel fastest?

Answer 4

Light travels fastest in gases as the molecules are far apart so they are least likely to interfere or be in the way of light particles.

Question 5

What is Kinetic Energy?

Answer 5

▪Kinetic energy is a form of energy that an object or a particle has by reason of its motion.

Question 6

Does the particles of gas have high or low kinetic energy?

Answer 6

▪The particles of gases have high kinetic energy
because the particles of gases move with high speed due to the large spaces and weak forces of attraction between the particles.
