Questions & Step-by-Step Solutions

For an ideal gas, which equation relates pressure, volume, and temperature?
Correct Answer: PV = nRT
  • Step 1: Understand that we are talking about an ideal gas, which is a theoretical gas that follows certain rules.
  • Step 2: Know that the relationship between pressure, volume, and temperature of an ideal gas is described by a specific equation.
  • Step 3: The equation is called the ideal gas law.
  • Step 4: The ideal gas law is written as PV = nRT.
  • Step 5: In this equation, P stands for pressure, V stands for volume, n is the number of moles of gas, R is a constant called the gas constant, and T is the temperature.
  • Ideal Gas Law – The relationship between pressure (P), volume (V), temperature (T), and the number of moles (n) of an ideal gas, expressed as PV = nRT.
