This book uses the Avogadro's LawĪvogadro's law describes the relationship between volume and the moles of gas in the sample. His law indicates a direct relationship between pressure and temperature: P1/T1 = P2/T2, where P stands for pressure, T stands for temperature, and the numbers refer to initial and final conditions.Īs temperature increases, particles move faster causing collisions with the sides of the container to happen more often and to be stronger. Gay-Lussac’s law describes the relationship between the temperature and pressure of an ideal gas under constant volume. The volume increases to keep the pressure constant. When temperature or average kinetic energy increases, particles move faster causing more and stronger collisions with the walls of the container. Charles' law indicates that there is a direct relationship between volume and temperature: V1/T1 = V2/T2, where V stands for volume, T stands for temperature, and the numbers refer to the initial and final conditions. Charles’ LawĬharles' law describes the relationship between the volume and temperature of an ideal gas under constant pressure. When volume decreases, the particles collide with the side of the container more often, thereby increasing pressure. It indicates an inverse relationship between pressure and volume: P1V1 = P2V2, where P stands for pressure, V stands for volume, and the numbers refer to the initial and final pressures and volumes. Boyle’s Lawīoyle's law describes the relationship between the pressure and volume of an ideal gas under constant temperature. The following relationships hold true when the amount of gas is constant. Gas laws are a set of laws that describe the relationship between pressure, volume, temperature, and moles of gas. Don't worry, we're providing some perfect responses to AP questions too□. You will often see this term on AP questions. ![]() ![]() STP, or Standard Temperature and Pressure, are conditions at 1 atm and 273.15 K. We can think of temperature as how fast particles are moving in a substance. Therefore, the higher the temperature of a substance, the greater the average kinetic energy of its particles. Temperature is a function of mass and velocity and it is most often seen as the average kinetic energy of particles in a substance on this AP exam. Standard pressure is a measure of the pressure exerted by the weight of the Earth's atmosphere at a particular location, and you may know it better as " atmospheric pressure." Standard Pressure: 1.00 atm = 760 mm Hg = 760 torr = 101.3 kPa The key phrase you want to associate with pressure is "the number of times particles hit the walls of the container." If you are ever asked to explain any of the relationships in this key topic, always mention that phrase if pressure is involved!īelow is the value for standard pressure in four different units. Gases exert pressure on their surroundings. What do you currently know about temperature and pressure? Let's expand on those definitions and start thinking about how gases respond to changes in pressure and temperature. ![]()
