CHARLE'S LAW

• TEMPERATURE - IT INCREASES, AS THE VOLUME INCREASES
• GAS PARTICLE - PARTICLES WHICH HAVE WEAK INTERMOLECULAR FORCE OF ATTRACTION
• CHARLE'S LAW - LAW THAT EXPLAINS THE RELATIONSHIP BETWEEN VOLUME AND TEMPERATURE AT A CONSTANT PRESSURE
• CHARLE'S LAW - THE TEMPERATURE INCREASES AS THE VOLUME ALSO INCREASES. THEY ARE DIRECTLY PROPORTIONAL TO EACH OTHER
• V1/T1=V2/T2 IS THE FORMULA FOR CHARLE'S LAW
• PRESSURE - IT IS A FORCE APPLIED BY GASES PER UNIT AREA
• TEMPERATURE - MEASURES THE COLDNESS OR HOTNESS OF GAS
• VOLUME - AMOUNT OF SPACE OCCUPIED BY GAS
• GASES HAVE DIFFERENT PROPERTIES:

  • INDEFINITE SHAPE AND SIZE
  • FIT THE SHAPE AND SIZE OF THEIR CONTAINERS
  • FAR FROM ONE ANOTHER
  • HIGHLY COMPRESSIBLE
  • ABLE TO FLOW
  • HAVE MASS, VOLUME, TEMPERATURE, AND PRESSURE
• GAS - IS THE STATE OF MATTER IN WHICH THE PARTICLES ARE FAR APART, FAST-MOVING AND NOT ORGANIZED IN ANY PARTICULAR WAY
• PRESSURE - THE FORCE APPLIED BY GAS PER UNIT AREA
• WHAT IS PRESSURE:

  • P=F/a
  • N/msquared or pascal (Pa) unit for pressure
  • at sea level, the average atmospheric pressure is 101kPa. 1atm is 101.324kPa
• 1 atm is equivalent to:

  • 760 mg HG
  • 76 cm HG
  • 76 cm HG = 760 torr
  • 101325 Pa
  • 101325 Pa = 14.6956 psi
• OXYGEN (O2) - IS A GAS WHICH HAS NO COLOR OR SMELL. IT IS A VERY IMPORTANT ELEMENT AS WE NEED IT TO LIVE, IT IS A PART OF AIR WE BREATHE, AND THE WATER WE DRINK
• what's the purpose of oil?

  it is to absorb vitamins
• what is the purpose of fats?

  it is to store energy
• what are the 3 types of carbohydrates?

  • monosaccharides
  • disaccharides
  • polysaccharides
• give 3 examples of food that are rich in protein.

  • meat
  • fish
  • egg
• what are the common monosaccharides?

  glucose and fructose
• sucrose or sugar is under what saccharides?

  disaccharides
• gas contains mass, temperature, pressure, and volume
• give me the 2 scientists.

  robert boyle and jacques charles
• describe the gas molecular force of attraction.

  weak/no bonds
• pure substance - are classified into elements and compounds
• mixture - classified into homogeneous and heterogeneous mixtures
• mixture is classified into 2

  • homogeeous
  • heterogenous
• matter - a substance that is made up of various types of particles that occupies physical space and has inertia
• pure substance - are a form of matter that has constant chemical composition and characteristics
• gas - a state of matter in which the particles are far apart, fast-moving, and not organized in any particular wau
• describe how number of molecules affect the pressure of gas - increase number of molecules also increases the pressure of a gas
• describe how volume affect the pressure of gas - reducing the volume of gas increases its pressure
• kelvin - the absolute temperature used in measuring gases
• give me the 3 factors that affects the pressure of gases.

  • number of molecules
  • volume
  • temperature
• Proteins contain - carbon, hydrogen, and oxygen, along with nitrogen, sulfur, and other nonmetals.
• Protein-rich foods like eggs, fish, meat, and cheese are broken down by the digestive system into amino acids.
• Amino acids - are the building blocks of proteins.
• There are 20 amino acids in human protein, with 11 synthesized by the body and 9 obtained from food. ↓
• the 9 amino acids that must be obtained from food are called essential amino acids
• protein-rich foods supply amino acids for cell repair and development
• Nucleic acids - code for hereditary traits and control protein production.
