Whatsa Matter? Do Now
Modern chemistry is defined as the study of matter.
•What do you think matter is?•Name 2 things that are matter and 2 things that are not matter.

What’s a Matter Worksheet
• Work together in groups of three to complete the “What’s a Matter” Worksheet.
• Come up with a group definition of “matter”

Some Textbook Definitions
• Matter is anything that has mass and volume.• Matter is anything of substance in the known
universe.• Matter is anything that takes up space.

So what about energy?
• Technically, energy is the “ability of a system to do work or supply heat”
• Comes is many forms: potential, kinetic, heat…• Informally, it is the movement of or effect of/on matterEX: Say you stand still and then you break into a
run…Has your matter changed??Has your energy changed??

Check-in
Which of the following can be classified as matter according to our definition?
• Beam of sunlight• Your breath• An automobile• Rain• An idea• Sadness

So what about FIRE?
• The ancient Greeks and alchemists thought it was an element.
• (They also considered earth, air, and water to be elements.)
• Fire is made up of many different substances, so it is not an element, fire is a mixture of hot gases.
• Flames are the result of a chemical reaction, primarily between oxygen in air and a fuel producing carbon dioxide, steam, light, and heat.
• If the flame is hot enough, the gases are ionized and become yet another state of matter: plasma.

What are the 4 states of matter?
•Solid•Liquid•Gas•Plasma

What the heck is plasma?
• closely related to gases • the particles are neither atoms nor molecules, but electrons
and positive ions. • Plasmas can be formed at very high temperatures• The resulting particles can then move freely, like the
particles in a gas. • found on Earth in the outermost atmosphere• probably more prevalent in the universe than all of the
other three states of matter. – The stars, comets' tails, and the aurora borealis are all plasmas.
• Because their particles are electrically charged, plasmas are greatly influenced by electric and magnetic fields.

Is that what’s in my “plasma” TV?
• A plasma display panel (PDP) • Many tiny cells between two panels of glass
hold a mixture of noble gases. The gas in the cells is electrically turned into a plasma which then excites phosphors to emit light. – Phosphors (not the element phosphorus) are
metallic compounds
