Questions & Step-by-Step Solutions
In which scenario does the ideal gas law (PV=nRT) fail to accurately predict gas behavior?
Step 1: Understand the ideal gas law, which is PV=nRT, where P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature.
Step 2: Recognize that the ideal gas law assumes that gas particles do not attract or repel each other and that they occupy no volume.
Step 3: Identify the conditions where the ideal gas law may not work well: low temperatures and high pressures.
Step 4: At low temperatures, gas particles move slowly, and intermolecular forces (attraction or repulsion between particles) become significant.
Step 5: At high pressures, gas particles are forced closer together, and their actual volume cannot be ignored.
Step 6: Conclude that under these conditions (low temperature and high pressure), the assumptions of the ideal gas law break down, leading to inaccurate predictions of gas behavior.
