M2 Topic 4: Gas Laws Flashcards
what are the properties of gases (4)
they will spontaneously fill a container
easily compressed
form homogeneous mixtures
spread far apart
what are the three main physical components considered when performing calculations relating to gases
pressure
volume
temperature
what is pressure
the force gas particles exert on their surroundings
what is pressure(P) measured in
kPa
what is volume(v) measured in
L
what is temperature(T) measured in
kelvin (K)
what are all the gas laws
Boyle’s law
Charles’ law
Gay-Lussac’s Law
Avogadro’s Law
what does Boyle’s law state
Volume(V) is inversely proportional to pressure(P) if temperature(T) is constant [V α 1/P]
what does Charles’ Law state
Volume(V) is proportional to Temperature(T) if Pressure(P) is kept constant [V α T]
what does Gay-Lussac’s Law state
Pressure(P) is proportional to Temperature(T) if volume(V) is kept constant [P α T]
what does Avogadros law state
Volume(V) is proportional to moles(n) if pressure(P) and temperature(T) are kept constant [V α N]
what is the Ideal Gas Law
PV =nRT
what is R in the ideal gas law
the gas constant
