1 Matter: A substance that has mass and volume (takes up space).
What is Matter? Matter: A substance that has mass and volume (takes up space).


3 Matter is Made up of Atoms
Center is the nucleus: contains protons and neutrons Electrons orbit the outside of the nucleus

4 Atom The smallest basic unit of matter Atoms are extremely small.
1 tsp of water = 500,000,000,000,000,000,000,000 atoms 5 x 10 23 500 sextillion

5 Molecules Molecules are made up of more than one atom. (they can be the same or different types)

6 PHASES OF MATTER Matter can exist as 4 different phases or states.
Solid Liquid Gas Plasma All living and non-living things are made of matter!

7 States of Matter

8 SOLID Has a definite volume and a definite shape. Examples: Rocks Desk

9 LIQUID has a definite volume but no definite shape. Water Blood Milk

10 GAS Has no definite volume and no definite shape.
Air (mixture of different gases) Water Vapor (water in a gas form)

11 Plasma Extremely hot temperatures
Atoms have lost or gained electrons; which gives them a charge and makes them ions Sun and Stars are in a plasma state

12 WAYS TO MEASURE MATTER Mass – the amount of matter in an object.
Measured in grams (g) and kilograms (kg) Volume – The amount of space an object takes up. Liquids: measured in milliliters (mL) and liters (L) Solids: measured in cm3

13 Is There a Difference between Mass and Weight?
YES!!! Mass: the amount of matter in an object. When you measure mass you are comparing a standard unit amount to the item. The standard unit used to measure mass is kg and g Weight: the amount of gravitational pull acting on an object Spring scale (measuring Newtons) and pounds

14 Example of Mass and Weight Difference
If you are on Earth and then on the Moon your mass would measure the same. Your weight would change because the gravitational pull is different in the two locations Earth Mass same Weight larger Moon Weight smaller

15 Volume Measurements Volume Formula
Volume= length ● width ● height (V=lwh) Example: A box has the length of 40 cm, width of 3 cm , and the height of 2 cm. Find the volume

16 Volume Identify (I): l=40cm, w=3cm, h= 2cm Formula (F):V=lwh
Substitute (S):V=(40cm)(3cm)(2cm) Math (M):V=240 Units (U): Volume= 240 cm3

17 Volume by Displacement ( Works with objects that fit into your measuring container)
Add water to a graduated cylinder Write down the initial volume Submerge irregular shaped object into cylinder Measure new water level Subtract the initial water level (smaller #) from the final water level (larger #)

18 CHANGES IN MATTER Matter will change phases when heat is added or lost. Melting: solid to a liquid (heat is added) Sublimation: solid to a gas (heat is added) Deposition: gas to a solid (heat is lost) Freezing: liquid to a solid (heat is lost) Condensation: gas to a liquid (heat is lost) Ionization: (extreme heat is added)
