Questions & Step-by-Step Solutions

For an ideal gas, which of the following is true at constant temperature?
  • Step 1: Understand that we are dealing with an ideal gas at constant temperature.
  • Step 2: Recall Boyle's Law, which states that for a given amount of gas at constant temperature, the pressure (P) and volume (V) are inversely related.
  • Step 3: This means that if the volume increases, the pressure decreases, and vice versa.
  • Step 4: The relationship can be expressed mathematically as PV = constant.
  • Step 5: If we have two different states of the gas, we can write this as P1V1 = P2V2, where P1 and V1 are the initial pressure and volume, and P2 and V2 are the final pressure and volume.
  • Boyle's Law – At constant temperature, the pressure and volume of an ideal gas are inversely related, meaning that as one increases, the other decreases, and their product remains constant.
