Which gas behaves most like an ideal gas under standard conditions? (2019)
Step 1: Understand what an ideal gas is. An ideal gas is a theoretical gas that perfectly follows the gas laws without any deviations.
Step 2: Know the conditions referred to as 'standard conditions.' This usually means a temperature of 0 degrees Celsius and a pressure of 1 atmosphere.
Step 3: Recognize that real gases can deviate from ideal behavior due to intermolecular forces and the size of the gas particles.
Step 4: Identify gases that are known to behave closely to ideal gases. Common examples include helium, neon, and hydrogen.
Step 5: Compare the properties of these gases. Helium is very small and has weak intermolecular forces, which means it behaves more like an ideal gas.
Step 6: Conclude that among the common gases, helium behaves most like an ideal gas under standard conditions.
