Q
Q: Which of the following statements about real gases is true?
Solution: Real gases can condense into liquids under certain conditions, unlike ideal gases which are assumed to have no volume and no intermolecular forces.
Steps: 5
Step 1: Understand what a real gas is. A real gas is a gas that does not behave perfectly according to the ideal gas laws due to interactions between gas molecules.
Step 2: Know what an ideal gas is. An ideal gas is a hypothetical gas that perfectly follows the ideal gas laws, meaning it has no volume and no intermolecular forces.
Step 3: Learn about condensation. Condensation is the process where a gas turns into a liquid, usually when the gas is cooled or compressed.
Step 4: Compare real gases and ideal gases. Real gases can condense into liquids when conditions like temperature and pressure are right, while ideal gases cannot condense because they are assumed to have no volume and no forces between molecules.
Step 5: Conclude that the statement about real gases condensing into liquids is true, while the statement about ideal gases not condensing is also true.
