Question 1
Question 2
Question 3
A) Which statement correctly describes the relationship between the volume of a gas and its
temperature, in Kelvin, assuming pressure is held constant? (1 point)
The relationship is directly proportional; as temperature increases, volume increases in the same way.
The relationship is directly proportional; as temperature increases, volume decreases in the same way.
The relationship is inversely proportional; as temperature increases, volume increases in the same way.
The relationship is inversely proportional; as temperature increases, volume decreases in the same way.
A) Which statement explains the molecular changes that occur in an enclosed gas as the pressure
increases and the temperature is held constant? (1 point)
An increase in pressure causes particles to move closer together, increasing the volume.
An increase in pressure causes particles to move farther apart, decreasing the volume.
An increase in pressure causes particles to move farther apart, increasing the volume.
An increase in pressure causes particles to move closer together, decreasing the volume.
A) The ideal gas law is represented by . As volume is held constant and the temperature
increases, how would the pressure be expected to change? (1 point)
PV = nRT
It would remain constant.
It would decrease.
It would become zero.
It would increase.
Question 4
Question 5
A) When the pressure of a gas decreases, which quantity will increase, assuming all other variables are
held constant? (1 point)
n
T
R
V
A) What must be true in order to use the conversion factor when performing a
stoichiometric calculation involving gases? (1 point)
22.7 L/mol
All of the gases involved must be the same type of element or compound.
The gases must all be composed of pure elements and not compounds.
The container holding the gases must be at standard temperature and pressure.
The coefficients of the gases in the chemical equation must all be the same.
