Boyle's Law relates which two variables at constant temperature?
A
Pressure and volume
B
Volume and temperature
C
Moles and volume
D
Pressure and temperature
Correct Answer: Option A — Pressure and volume
Explanation:
Boyle's Law states that at constant temperature, the pressure of a fixed amount of gas is inversely proportional to its volume, meaning PV remains constant when temperature and moles are unchanged.
