Question: What is the effect of increasing the number of moles of gas in a closed container at constant temperature?

Options:

  1. Pressure decreases
  2. Pressure increases
  3. Volume decreases
  4. Temperature decreases

Correct Answer: Pressure increases

Solution:

According to Avogadro\'s Law, increasing the number of moles of gas increases the pressure if the volume is constant.

Questions & Step-by-Step Solutions

What is the effect of increasing the number of moles of gas in a closed container at constant temperature?
Correct Answer: Pressure increases.
  • Step 1: Understand that a closed container means no gas can enter or leave.
  • Step 2: Know that temperature is constant, which means the energy of the gas particles doesn't change.
  • Step 3: Recognize that 'moles of gas' refers to the amount of gas present in the container.
  • Step 4: Remember Avogadro's Law, which states that if you increase the number of moles of gas in a fixed volume, the pressure will increase.
  • Step 5: Conclude that adding more gas molecules causes more collisions with the walls of the container, leading to higher pressure.
