q.13. what state of matter is mercury (element) at room temperature?
a) solid b) liquid c) gas

Explanation:

• Q.5: In solids, particles are closely packed due to strong intermolecular forces.
• Q.6: Liquid particles are close but can move past each other (Container Y).
• Q.7: Solids have the slowest - moving particles as they vibrate in place.
• Q.8: Particles in a liquid have more energy than those in a solid.
• Q.9: Gases have the weakest attractive forces between particles.
• Q.10: Apple and banana are solids; others have non - solid states.
• Q.11: Sand is a solid (not a liquid).
• Q.12: Water vapor is a gas.
• Q.13: Mercury is a liquid at room temperature.
