Boyle’s law can be represented as?
All are
V ∝ 1/P at constant T.
PV = constant.
P ∝ 1/V at constant T.
Three key relationships which exist among the four gas variables are?
Boyle’s, Charles’s, and Henry’s laws
Boyle’s, Charles’, and Graham’s laws
Boyle’s, Charles’, and Dalton’s laws
Boyle’s, Charles’, and Avogadro’s laws
Each of the gas laws focuses on the effect that changes in one variable have on gas volume, which is correct?
All of the above
Avogadro’s law focuses on amount (number of moles) of gas ( V ∝ n)
Charles’s law focuses on temperature (V ∝ T)
Boyle’s law focuses on pressure (V ∝ 1/P)
What happens at S.T.P?
T = 0
o
C or 273.15 K
P = 1 atm or 760 mmHg or 101325 Pa
All of the above
Molar volume is 22.4 dm3 or 22.4 litres
Combining Boyle’s, Charles’, and Avogadro’s gas laws gives one relationship, called?
Molar gas constant
The gas hypothesis
The gas law
The ideal gas law (or ideal gas equation)
