Answer: Stronger forces increase resistance between flowing layers of liquid.
- A Stronger intermolecular forces cause the liquid's molecules to move noticeably faster
- B Stronger forces increase resistance between flowing layers of liquid
- C Stronger intermolecular forces actually lower the liquid's surface tension
- D Stronger intermolecular forces increase the liquid's equilibrium vapour pressure
Correct answer: B. Stronger forces increase resistance between flowing layers of liquid
Explanation: Stronger intermolecular attraction increases internal friction between adjacent layers of liquid, raising viscosity.
Boyle's law: at constant temperature the pressure of a fixed mass of gas is inversely proportional to its volume (P ∝ 1/V), so the P–V plot is a hyperbola — halving the volume doubles the pressure. Image: Reginaprice2013, CC BY-SA 3.0, via Wikimedia Commons.
