P1T1 = P2T2
P1/V1 = P2/V2
P1V1 = P2V2
T1/V1 = T2/V2
Answer is Right!
Answer is Wrong!
The correct answer is C. $P_1V_1 = P_2V_2$. This is the ideal gas law, which states that for a fixed amount of an ideal gas kept at a fixed temperature, pressure and volume are inversely proportional.
Option A is incorrect because it does not take into account the volume of the gas. Option B is incorrect because it does not take into account the pressure of the gas. Option D is incorrect because it does not take into account the temperature of the gas.
The ideal
gas law is a good approximation for many gases at low pressures and high temperatures. It is not a good approximation for gases at high pressures or low temperatures, where the gas molecules interact with each other in a more complex way.
