5.3 Simple Gas Laws Flashcards
What are the simple gas laws, define each laws function, and state the equations?
The simple gas laws express relationships between pairs of variables when the other variables are held constant.
Boyle’s law is states that the volume of a gas is inversely proportional to it’s pressure when temperature (in Kelvin) and moles are constant.
P(1)V(1) = P(2)V(2)
Charles’s law states the volume of a gas is inversely proportional to its temperature (in Kelvin) when pressure and moles are constant.
V(1)/T(1) = V(2)/T(2)
Avogadro’s law states that the volume of a gas is directly proportional to the amount (in moles) when pressure and temperature (in Kelvin) are constant.
V(1)/n(1) = V(2)/n(2)
What is Boyle’s law?
Boyle’s law is states that the volume of a gas is inversely proportional to it’s pressure when temperature (in Kelvin) and moles are constant.
P(1)V(1) = P(2)V(2)
What is Charles’s law?
Charles’s law states the volume of a gas is inversely proportional to its temperature (in Kelvin) when pressure and moles are constant.
V(1)/T(1) = V(2)/T(2)
What is Avogadro’s law?
Avogadro’s law states that the volume of a gas is directly proportional to the amount (in moles) when pressure and temperature (in Kelvin) are constant.
V(1)/n(1) = V(2)/n(2)
What is the molecular interpretation of Boyle’s law?
As the volume of a gas sample decreases, gas particles collide with surrounding surfaces more frequently, resulting in greater pressure.
What is the molecular Interpretation of Charles’s law?
If a balloon is moved from an ice water bat to a boiling water bath, its volume will expand as the gas particles within the balloon move faster (due to the increased temperature in Kelvin) and collectively occupy more space.
What can we assume with Avogadro’s law, and how can assumption’s relationship be described mathematically?
Avogadro’s law assumes constant temperature (in Kelvin) and pressure, and is independent to the nature of the gas. This relationship between volume and amount (in moles) is linear.
