Science (L1)

• Gas

  • is a state of matter where the particles are spread out it has no definite shape or volume
• Kinetic Molecular Theory

  • It was proposed by Ludwig Boltzmann and James Maxwell. They found out that we can understand the behavior of gases in terms of the motion of individual molecules
• Kinetic Energy Measurement

  • Joules (J)
• • Kinetic Molecular Theory (2nd)

  A gas consists of very small particles that are in constant, random, and straight-line motion
• • Kinetic Molecular Theory (1st)

  The particles of a gas are separated by distances much larger than their size
• • Kinetic Molecular Theory (3rd)

  The particles of an ideal gas exert no attractive forces on one another or on their surroundings
• • Kinetic Molecular Theory (4th)

  Average Kinetic Energy of gas particles is proportional to the absolute temperature
• Volume

  • It refers to the amount of space being occupied by the object
• Pressure

  • It refers to the force applied per unit of surface area
• Temperature

  • The average kinetic energy of the particles
• Amount of number of Moles

  • It is the amount of substance that comprises matter
• Gas Laws

  • It aims to provide relationships between and among the different measurable properties of gases
• Boyle's Law

  • In the 17th century an irish chemist Robert Boyle investigated the relationship between pressure and volume of a gas. In his discovery he used J-tube to show the relationship between the properties of gases
• Gay-Lussac's Law

  • This law states that pressure and temperature of gas is directly proportional to each other under constant volume
• Joseph Louis Gay-Lussac

  • A French Chemist investigated the relationship between temperature and pressure
• Robert Boyle

  • In the 17th century an irish chemist investigated the relationship between pressure and volume of a gas. In his discovery he used J-tube to show the relationship between the properties of gases
• Charles Law

  • This law states that volume and temperature is directly proportional to each other with constant pressure
• Jacques Charles

  • A French mathematician physicist inventor and balloonist investigated the relationship between volume and temperature of an ideal gas at constant pressure
