A gas is held at constant temperature and its pressure is doubled. What happens to its volume?
Answer and explanation
Correct answer: D. It is halved
- Step 1: Boyle's law states that P x V is constant at constant temperature. Step 2. Doubling P halves V. Answer: it is halved. Why not the others: Boyle's law states that gas pressure is inversely proportional to volume at constant temperature; doubling volume cuts pressure in half, while quadrupling volume lowers pressure fourfold.
