Understanding the Answer
Let's break down why this is correct
Answer
In the ideal gas law, pressure and volume are inversely related when temperature and the number of molecules stay the same, so a higher pressure means a smaller volume. Temperature, on the other hand, is directly proportional to pressure when volume is fixed. This means that if you double the pressure while keeping volume constant, the temperature also doubles. For example, if a gas in a sealed container has its pressure raised from 1 atm to 2 atm while the volume stays the same, the temperature will rise from 300 K to 600 K. Thus, Temperature : Pressure.
Detailed Explanation
In the Ideal Gas Law, pressure is directly proportional to temperature when the amount of gas stays the same. Other options are incorrect because Density means mass divided by volume; it doesn’t change in the same way that temperature changes pressure; The number of molecules (n) is part of the equation, but it stays the same when you only change temperature.
