What is the effect of increasing the number of moles of a gas on its pressure at constant volume and temperature?
Pressure decreases
Pressure increases
Pressure remains constant
Pressure becomes zero
According to the ideal gas law, increasing the number of moles (n) of a gas while keeping volume (V) and temperature (T) constant will increase the pressure (P).

Q: What is the effect of increasing the number of moles of a gas on its pressure at constant volume and temperature?
Solution: According to the ideal gas law, increasing the number of moles (n) of a gas while keeping volume (V) and temperature (T) constant will increase the pressure (P).
Steps: 6
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.
