Gas

• Chemistry deals with the properties of substance and the changes they undergo
• Matter is anything that has mass and volume or occupy space
• Energy does not occupy space
• The states of matter are solid, liquid, gas, plasma, and Bose Einstein condensate
• This is a state of matter that forms in high temp

  Plasma
• Plasma is composed of electrons and nucleus
• This is a state of matter that forms in a absolute cold temperature, usually in labs

  Bose Einstein condensate
• What are the two main factors to determine state

  Force and kinetic energy
• What state of matter has the high force of attraction

  Solid
• What state of matter has the highest kinetic energy

  Gas
• Kinetic energy means energy in motion and tends to pull apart
• The meaning of kinetic is motion
• Gases are fluid
• Gases expand and feel any container
• Gases have low density
• It is a characteristic of gas that has the ability to flow in small spaces

  Effusion
• Characteristic of gas that has the ability to spread


  Diffusion
• Particles move in random direction and constant straight line
• All collision of particle are elastic meaning that kinetic energy is transferred without loss of energy
• The factors affecting gas pressure are amount of gas volume and temperature
• Atmospheric pressure where the gas molecules in the atmosphere are pulled towards the Earth due to gravity exerting pressure
• Barometer measures atmospheric pressure
• What is the value of atmosphere

  1 atm
• What is the value of kilopascal?

  101.325kPa
• What is the value of millimeter of Mercury

  760 mm Hg
• Value of torr


  760 torr
• The standard unit of pressure is atmosphere
• The standard unit of temperature is Kelvin
• If you are going to convert Celsius to Kelvin what will be the formula? 

  K= C + 273
• If you're going to convert Kelvin to Celsius what will be the formula

  C= K -273
• Kelvin is the absolute temperature
• Lord Kelvin is the one who invented the absolute temperature
• Boyle's law is inversely proportional at constant mass and temperature
• How many decimals do we add in the final answer lf Boyle's law?

  2 decimals
• How many decimals do we add in the final answer of Charles' law?

  1 decimal
• How many decimals do we add in the final answer lf Gay Lussac's law?

  2 decimals
• Charles law states that an increase in temperature leads to an increase in volume, in short Volume is directly proportional to temperature at a constant mass and pressure
• Always convert the value of each unit of temperature before solving the whole problem
• This is a gas law where in the temperature rises so does the pressure, in short the pressure and absolute temperature are directly proportional

  Gay-Lussac's law
