Answer 7

Surface particles of a liquid change to a gas at a temperature below its boiling point

Question 8

Solvent

Answer 8

Liquid that a solute dissolves in

Question 9

Solute

Answer 9

Substance that dissolves in the solvent

Question 10

Solution

Answer 10

Mixture formed when a solute dissolves in a solvent

Question 11

Solubility

Answer 11

Mass of a solute that can dissolve in a solvent at any given temperature. Units per 100 grams of solvent

Question 12

Saturated solution

Answer 12

Solution that contains as much dissolved solid as possible at a particular temperature

Question 13

What is the particles in a solid

Answer 13

• regular arrangement in a lattice
• particles vibrate but dont move freely
• lowest energy
  -bond easy to break

Question 14

What is the particle arrangement of a liquid

Answer 14

• random arrangement but touching
• particles move freely but remain touching
• medium energy
• intermolecular forces- easy to break with high energy

Question 15

Particle arrangement of a gas

Answer 15

• random arrangement and spread out
• particles move freely and fast
• highest energy

Question 16

Explain why hot water evaporates more quickly than cold water

Answer 16

• particles will have higher kinetic/ heat energy- Hot water molecules move faster, so more have enough energy to evaporate.
  • Increased Evaporation Rate: More molecules at the surface escape into the air.
  • Faster Vapor Diffusion: Water vapor spreads quickly, allowing continuous evaporation.
  • Weaker Intermolecular Forces: Heat weakens hydrogen bonds, making it easier for molecules to escape.
