Objectives

Objective 1: Measuring Matter

1. Whenever you go to a different place your weight changes, but when you travel to a       different place your mass never changes; it is more accurate to go by mass.

2. 619.65cm3

3. cm3 or ml3

4. m/v or g/cm3

5. L * W * H

Objective 2: Changes in Matter

1. Chemical Change- when bonds are formed or broken between atoms (a new substance is formed)

   Physical Change- a change not involving a change in the substance’s chemical identity (no new substances are formed)

2. - solid is made

    - object changes color

    - gasses are formed

    -  heat, light, and sound are made

3. The conservation law of mass describes that mass in a container stays the same as it first was over time.  Epicurus created this law; he was an ancient Greek philosopher.

4. Thermal energy is actual energy, while temperature isn’t energy.  Also thermal energy is the total amount of kinetic energy contained in all the particles of a substance and temperature is the average kinetic energy of the particles in a substance.

5. Exothermic Reaction- Elephant Toothpaste, Ashley and I did this and it made the bottle really hot

    Endothermic Reaction- mixing water and ammonium nitrate makes the substance get cold over time

Objective 3: Energy and Matter

1. Chemical, thermal, potential, electromagnetic, kinetic, and electrical energy all relate to the change in matter.

2. Kinetic Energy

3. Potential Energy

4. Electromagnetic energy is energy from radiation.  It can transfer waves of energy to different places and it can do this in the form of heat, light, or sound.

5. Electrical energy, an example of this is when you plug in a phone charger… you plug it into the wall and then the electrons go to the phone to power it up.

Objective 5: Boyle’s Laws

1. His law talks about pressure and volume of a gas.

2. This is so because when a balloon goes higher into the altitude, its pressure decreases.  If you fill it up all the way it will expand and soon pop.

3. Pressure goes down and Volume goes up

4. His law applies to physicians in many ways, one way is our diaphragm.  As the diaphragm lowers, the lungs grow bigger because of little pressure.  The diaphragm then applies some pressure and carbon dioxide.  This soon leaves the body because the volume of the lungs decreases.

5. They rely on it because they need to know how much oxygen they need.

Objective 6: Charles’ Law

1. His law describes how gases expand when they are heated.

2. As the temperature of gas increases, the gas molecules move more quickly

3. Jacque Charles

4. In 1783, he landed and a bunch of people attacked it and ruined it.

5. V100 - V0 = KV0  the K is kept unchanged…
