What is the effect of increasing the number of moles of a gas on its pressure at constant volume and temperature?
Step 1: Understand the ideal gas law, which is represented by the equation PV = nRT.
Step 2: Identify the variables in the equation: P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature.
Step 3: Note that in this scenario, volume (V) and temperature (T) are kept constant.
Step 4: Recognize that if you increase the number of moles (n) of the gas, the left side of the equation (PV) must also increase to keep the equation balanced.
Step 5: Since volume (V) is constant, an increase in the number of moles (n) will result in an increase in pressure (P).
Step 6: Conclude that increasing the number of moles of a gas at constant volume and temperature will lead to an increase in pressure.
