III. MassA. What is Mass?- The amount of matter found in an object- It is always constant- Can only change when matter is added or

taken away1. Mass and Inertia

a. Inertia: is measured by mass, it is the resistance an object has to a change in motion

b. The more mass the greater the inertiac. The force needed to overcome the inertia must

be great

B. What is weight?Weight is not constantIt can change according to conditionsThe pull of gravity on an object determines the

object’s weightYou weigh less on the top of a mountain than at

sea level1. Why?

a) As the distance between an object and the Earth increases there is gravitational force decreases!

b) You can become weightless!

SWBAT:• Describe four states of matter •Convert metric units

D. States of Matter1. 4 states of matter: Solid, liquid, gas and plasma

1. Solid: Definite shape and definite volume Tightly packed and can vibrate Structure is a regular repeating pattern know as a

crystal. Some solids do not keep definite shapes and they are

called amorphous

2. Liquid: Particles can move freely, has no definite shape Takes shape of it’s container Has viscosity: the resistance of a liquid to flow

3. GasesDoes not have a definite shape or definite volumeGas particles spread away from each other and

can be pushed very close togetherThey are in constant motion

4. PlasmaVery dangerous and extremely high in energy Most commonly found in the universeThe stars and sun contain matter in the plasma

September 20th

Homework:Read textbook pgs 39-

55, pg 48 #1-2, pg 54 #1-2

Do Now:

1. Take a Do Now sheet found on Mrs. Fugarino’s desk.

2. Quietly, read the Do Now and answer the questions.

SWBAT:• Explain the term density • Explain why matter floats or sinks• Apply your knowledge of density to your life daily!• Relate viscosity to density

E. Density and VolumeDensity = Mass/Volume

1.Density It provides a way to convert between mass

and volume of a substance. Density can be either expressed as

liquids (g/mL) or solids (g/cm3)

Density is an important property used to compare matter more accurately than just mass.

Chemistry Density Problems

density chart

Practice Questions1. A bar of aluminum has a volume of 1.45

cm3and a mass of 3.92 g. What is it’s density?

2. An object has a mass of 206 g and a volume of 250 mL. Calculate the density.

3. The density of silver is 10.5 g/cm3. What is the mass of the sample of silver if it has

a volume of 16.3 cm3?

Answers1. D = 2.7 g/cm3

2. D = 0.8 g/mL

3. Set up conversion factor:Density = 10.5 g/1cm3

mass/volume = 10.5 g/1cm3

mass/16.3 mL = 10.5 g/1cm3

171.2 g =16.3 cm3 x (10.5 g/1 m3 )

1. What is the formula for density?

2. Solve: A sample of gold has a mass of 96.5 g and a volume of 5 cm3. Calculate the density.

3. Solve: A liquid has a mass of 206 g and a volume of 250 mL. Calculate the density.

4. Solve: A sample of matter has a volume of 4.0 cm3 and a mass of 42 g. Calculate the density.

2. Quietly, read the Do Now and answer the questions.

SWBAT:• calculate volume of irregular and regular solids and liquids• practice rounding to the nearest tenth place• practice labeling with correct units when finding volume

Do Now: Going Backwards?1. A sample of vegetable oil has a density of 0.916

g/mL.

(a) What is the mass of the vegetable oil if the volume is 225 mL? (b) What is the volume of the vegetable oil if the mass is 45.0 g?

Answer(a) Density = 0.916g/mLSet up Conversion Factor:

0.916 g225.0 mL x 1mL = 206.0 g oil

(b) Density = 0.916 g/mLSet up Conversion Factor:

1mL45.0 g x 0.916 g = 49.1 mL

Density of fresh water is 1g/mL

Why do objects float in water?

Any matter having density less than 1g/mL will float

Only 11% of ice is actually ice, the other 89% is cold water

That is why ice cubes float!

Practice Questions4. A student measured the volume of an iron

nail to be 0.880cm3. She found that the its mass was 6.92g. What is the density of iron?

Answer4. Take the ratio of mass to volume.

6.92gD = 0.880cm3

= 7.86g/cm3

C. What is gravity?the force of attraction between an objectThe metric unit of weight is the newton (N)For every 1 kilogram there is 9.8 N

Solve: The mass of 55.5 kilograms is equal to how many Newtons?

Answer:55.5 kg (9.8N/1kg) = 543.9 N
