Classwork: Energy of Matter
Part 2. Chemical vs. Thermal Energy
Directions: Determine if each statement describes an example of chemical or thermal energy.
Put the correct letter in the blank. Use C for chemical energy and T for thermal energy.
_____ 8. A form of potential energy
_____ 9. Stored in the bonds that form a molecule
_____ 10. The warmth from the sun
_____ 11. A battery, which can be used to provide power to a TV remote control
_____ 13. All the heat in an oven that is “turned on” and being used to bake a pie
_____ 14. A hot cup of hot chocolate that is so hot it burns your hand
_____ 15. Gasoline, which sits in a gas tank waiting to be used as fuel for a car
_____ 16. A form of kinetic energy
_____ 17. A wood log that will be used later in a bonfire
_____ 18. The molecule ATP, which releases energy for chemical reactions in our body if one
of its chemical bonds is broken
Part 3. Energy of States of Matter
19. The three states (or phases) of matter are: ____________, __________, and _________
20. The _____________ state of matter has a defined measurable volume but no defined
shape, which is why it can “drip” or “spill”.
21. The _____________ state of matter has no defined shape and no defined volume because
its molecules can easily disperse or spread through the air.
22. The ____________ state of matter has a defined shape and volume, and often feels “hard”.
23. Which shows the correct order of the three states of matter from greatest to least amount of
kinetic energy?
A. Liquid, solid, gas
B. Solid, liquid, gas
C. Gas, liquid, solid
D. Gas, solid, liquid
Part 4. Review of Matter
24. The basic unit of matter is called an a__________.
25. A substance that is made of all of the same types of atoms is called an e_________.
26. When more than 1 atom are chemically bonded together, it forms a m___________.
27. All matter has ___ and occupies space. The simplest form of matter containing only
one type of atom with its own particular set of properties is called a(n) ___. A
combination of two or more atoms that can be the same or different is called a(n) ___.
Such combinations of atoms are held together by attractive forces, which help determine
the ___ of matter.
A. mass; particle; element; mass
B. mass; element; molecule; state
C. elements; atom; molecule; mass
D. molecules; element; particle; state
