Questions & Step-by-Step Solutions
If the volume of a gas is doubled while keeping the temperature constant, what happens to the pressure?
Correct Answer: Pressure is halved.
Step 1: Understand that we are dealing with a gas and its properties: volume, pressure, and temperature.
Step 2: Remember Boyle's Law, which states that for a given amount of gas at constant temperature, the pressure of the gas is inversely proportional to its volume.
Step 3: This means that if the volume increases, the pressure decreases, and vice versa.
Step 4: In this question, the volume of the gas is doubled. This means the new volume is twice the original volume.
Step 5: Since the volume is doubled, according to Boyle's Law, the pressure must decrease to maintain the relationship.
Step 6: Specifically, if the volume is doubled, the pressure is halved.
