Questions & Step-by-Step Solutions
What is the effect of increasing the number of moles of gas on the pressure, assuming volume and temperature are constant?
Correct Answer: Pressure increases.
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.
