Understanding Changes of State in Chemistry

What is the arrangement of particles in a solid like ice?

• In a lattice structure

• In a zigzag pattern

• Randomly scattered

• In a circular pattern

During the melting of ice, what happens to the particles?

• They gain energy and vibrate more

• They start to vibrate

• They lose energy and vibrate less

• They stop moving

What is the key change in particle behavior when a liquid boils?

• Particles lose energy and move closer

• Particles gain energy and move faster

• Particles stop moving

• Particles form a lattice structure

Which statement is true about the boiling process?

• Particles lose energy

• Particles move closer together

• Particles gain kinetic energy

• Particles form a solid

What happens to particles during condensation?

• They gain energy and move apart

• They lose energy and move closer

• They stop moving

• They form a lattice structure

What is the process called when a liquid turns into a solid?

• Condensation

• Freezing

• Boiling

• Melting

What role do forces of attraction play in the state of matter?

• They hold particles together

• They have no effect

• They only affect gases

• They repel particles

How do particles overcome forces of attraction during heating?

• By gaining energy

• By stopping movement

• By losing energy

• By forming a lattice

What is incorrect about saying particles 'start to vibrate' during heating?

• Particles are already vibrating

• Particles only vibrate in gases

• Particles stop vibrating

• Particles never vibrate

What happens to the forces of attraction when a solid is heated?

• They only affect liquids

• They disappear completely

• They are overcome by energy

• They become stronger
