Day one
Get to know each other
Day two
What Is Chemistry and Why Do We Study It?
Chemistry is the study of matter and how matter combines, changes shape or forms others substances
Beganings
Chemistry comes from Alchemy which was essentially philosophy
Egg in a bottle
Drop an alcohol soaked cotton ball in a flask and quickly place an egg covering the mouth of the Flask
Result:
Egg is sucked into the bottle
Reason:
Gali sacks law:
Temperature and pressure are inversely related
The Kinetic Molecular Theory of Gas
Particles make up all phases of matter are are made of atoms or molecules
To create a solid particles are packed together tightly
To create a liquid the particles are bonded but able to move more freely
To create a gas the particles move rapidly and are not bonded
If a has follows all the the rules of The Kinetic Theory of Gas it is an “Ideal Gas”
Thermometers
Heat makes Liquid Expand
Cold makes Liquids shrink
Temperature has the same effect on gas
The point where a substance melts or freezes is called The Melting Point
The point where it boils or condenses to a liquid is called The Boiling Point
Rules
Absolute Zero

- Matter is anything that has mass and takes ups space

Rules
- Gases consist of very small particles that are far apart relative to their size
- Gas particles are in constant random motion
- Collisions between gas particles and container walls are elastic collisions
- Elastic means that the particles bounce and retain their kinetic energy
- Inelastic collisions are collisions that destroy or stop all of the kinetic energy of all objects involved
- Inelastic collisions are collisions that destroy or stop all of the kinetic energy of all objects involved
- Elastic means that the particles bounce and retain their kinetic energy
- There are no forces of attraction or repulsion between gas particles
- Gases will not clump together
- Gases will not clump together
- The average kinetic energy of gas particles depends on the gas’s temperature
- Hotter means faster
- Hotter means faster
- Expandability: Gases will expand to fill any space given
- The act of gases expanding is called diffusion
- The act of gases expanding is called diffusion
- Compressibility: Gases can be compressed
- Boiling point of water: 100
- Body temperature: 37
- Water Freezes 0
- Boiling point of water: 212
- Body temperature: 98.6
- Water Freezes 32
Absolute Zero
- As volume decreases as temperature does, it would seem impossible to have a negative volume meaning that, Absolute zero is as cold as it can possibly be
- Absolute zero is hypothesized to be at -273.15C
- A kelvin is the same unit as Celsius but plus 273
- K = C + 273
- It is used to have absolute zero as 0
