D
The pressure will triple.
Understanding the Answer
Let's break down why this is correct
Answer
Gay‑Lussac’s Law says that when a gas’s volume is fixed, its pressure changes in direct proportion to its temperature. So if the temperature goes from 300 K to 600 K, the ratio of the final to initial pressure is 600 K ÷ 300 K, which equals 2. That means the pressure will double. For example, if the gas starts at 1 atm at 300 K, it will rise to about 2 atm when the temperature reaches 600 K.
Detailed Explanation
When the volume of a gas does not change, its pressure rises linearly with temperature. Other options are incorrect because The idea that pressure stays the same ignores the fact that temperature feeds energy into the gas molecules; Thinking pressure decreases assumes hotter gas pushes outward less, but in fact hotter gas pushes harder.
