What is the effect of increasing the number of moles of gas on the pressure, assuming volume and temperature are constant?
Pressure decreases
Pressure increases
Pressure remains constant
Pressure becomes zero
According to Avogadro's Law, increasing the number of moles of gas increases the pressure if volume and temperature are constant.

Q: What is the effect of increasing the number of moles of gas on the pressure, assuming volume and temperature are constant?
Solution: According to Avogadro's Law, increasing the number of moles of gas increases the pressure if volume and temperature are constant.
Steps: 4
Step 1: Understand that a 'mole' is a unit that measures the amount of gas.
Step 2: Remember that pressure is the force that gas molecules exert on the walls of their container.
Step 3: Know that Avogadro's Law states that if you increase the number of moles of gas, the pressure will increase, as long as the volume and temperature stay the same.
Step 4: Visualize a balloon: if you add more air (more moles of gas) into the balloon without changing its size (volume) or temperature, the pressure inside the balloon will rise.
