Here are the answers to your questions based on the provided options:
**Question 1:**
A) Which statement correctly describes the relationship between the volume of a gas and its temperature, in Kelvin, assuming pressure is held constant?
- **Answer:** The relationship is directly proportional; as temperature increases, volume increases in the same way.
**Question 2:**
A) Which statement explains the molecular changes that occur in an enclosed gas as the pressure increases and the temperature is held constant?
- **Answer:** An increase in pressure causes particles to move closer together, decreasing the volume.
**Question 3:**
A) The ideal gas law is represented by PV=nRT. As volume is held constant and the temperature increases, how would the pressure be expected to change?
- **Answer:** It would increase.
**Question 4:**
A) When the pressure of a gas decreases, which quantity will increase, assuming all other variables are held constant?
- **Answer:** V (Volume)
**Question 5:**
A) What must be true in order to use the conversion factor 22.7 L/mol when performing a stoichiometric calculation involving gases?
- **Answer:** The coefficients of the gases in the chemical equation must all be the same.
