Chemistry - temperature, pressure, volume, and gaseous

• The Fahrenheit temperature scale is named for German physicist Daniel Gabriel
• A gas is a substance that is in a gaseous, or vaporous, state of matter.
• The word “kinetic” means motion.
• The kinetic molecular theory describes the behavior of matter in terms of particles

  in motion.
• An ideal gas is defined as a gas that obeys gas laws at all conditions of pressure and

  temperature.
• A real gas is defined as a gas that does not obey gas laws at all standard pressure

  and temperature conditions.
• true - Gas pressure is caused by the force exerted by gas molecules colliding with the

  surfaces of objects
• true - An important property of natural gas is its pressure.
• Standard temperature is defined as zero degrees Celsius
• An important property of Gas is temperature.
• true - Pressure is a property that determines the direction in which mass flows.
• true - Pressure is a force exerted by the substance per unit area on another substance.
• True - Volume is the space occupied by matter.
• Boyle’s Law constant condition T
• Charles Law constant condition P
• Gay-Lussac’s Law constant condition V
• Combined Gas Law constant condition N
• Avogadro’s Law P/T
• Dalton’s Law T/V
• Graham’s Law T
• P = pressure
• V = volume
• T = temperature
• n = chemical amount
• R = ideal gas constant
• STP = standard temperature and pressure
• True - A gas that occupy a space have a pressure of some measurable degree.
• True - Gas perfectly in the ideal state.
