Test 1 - Matter and energy

Question 1

What is Matter?

Answer 1

-Matter is anything that takes up space and has mass.

Question 2

States of Matter - How they are different from one another

Answer 2

-Solid, liquid and gas. Gas molecules are well spread out and move quickly, it has no defined shape. Liquids are closer together and moes slower, it can change shape depending on its container but it can’t expand and get bigger naturally. Solid molecules are tightly packed together, it can’t change shape without being forced to.

Question 3

Changes in States - explain how the movement of the particles change

Answer 3

• When something is being heated up the molecules in it are moving further and further away from each other, they are also getting quicker. When something is being cooled down the molecules start to get closer and closer together, they are also becoming slower and slower.

Question 4

What is Energy?

Answer 4

-Energy is a property of matter, it’s not a physical object. Energy can not be created nor destroyed.

Question 5

What are the two forms of energy?

Answer 5

-the two forms of energy are kinetic and potential energy.

Question 6

What is the difference between Kinetic and Potential energy?

Answer 6

-Potential energy is stored energy waiting to be released, kinetic energy is energy you get while in motion.

Question 7

Give two examples of potential energy

Answer 7

-Chemical and elastic energy.

Question 8

What are the differences between Matter and Energy?

Answer 8

-Matter takes up space, matter can be destroyed and matter is visible. Energy does not take up space, can’t be destroyed and is invisible (mostly).
