Questions & Step-by-Step Solutions
What is the effect of increasing the number of moles of gas in a closed container at constant temperature and volume?
Correct Answer: Pressure increases.
Step 1: Understand that a closed container means no gas can enter or leave.
Step 2: Know that temperature is kept constant, meaning the gas is not getting hotter or colder.
Step 3: Recognize that volume is fixed, so the space inside the container does not change.
Step 4: Learn about moles of gas, which is a way to measure the amount of gas present.
Step 5: According to Avogadro's Law, if you increase the number of moles of gas in the container, the gas particles will collide more often with the walls of the container.
Step 6: More collisions with the walls of the container lead to an increase in pressure.
Step 7: Therefore, increasing the number of moles of gas at constant temperature and volume results in higher pressure.
