Question

what is boyles law?
boyles law refers to the relationship between pressure and temperature of a gas
boyles law is the study of how gases react to changes in temperature
the pressure of a gas is directly proportional to its volume when the temperature and the amount of gas are held constant
the pressure of a gas is inversely proportional to its temperature when the volume and the amount of gas are held constant
the pressure of a gas is inversely proportional to its volume when the temperature and the amount of gas are held constant

Explanation:

Boyle's Law states that for a given mass of an ideal gas at a constant temperature, the pressure \(P\) and volume \(V\) are inversely proportional. Mathematically, \(P_1V_1 = P_2V_2\) (where \(P_1\), \(V_1\) are initial pressure and volume, and \(P_2\), \(V_2\) are final pressure and volume). The key elements are pressure - volume relationship (inverse proportion) with temperature and amount of gas constant.

• First option: Incorrect as it mentions pressure - temperature (Boyle's Law is pressure - volume).
• Second option: Incorrect as it focuses on temperature change effect (not pressure - volume).
• Third option: Incorrect (direct proportion, while Boyle's is inverse).
• Fourth option: Incorrect (mentions pressure - temperature inverse, wrong relationship).
• Fifth option: Correct as it states pressure is inversely proportional to volume (with \(T\) and \(n\) constant).

Answer:

The pressure of a gas is inversely proportional to its volume when the temperature and the amount of gas are held constant.
