Describe the changes in temperature and molecular movement in each of the following changes:

Question

Boiling
Melting
Freezing
Sublimation
(simplify the answer)

Answer 1

Sure! Here's a simplified explanation of changes in temperature and molecular movement during each process:

Boiling

• Temperature: Increases until the boiling point.
• Molecular Movement: Molecules gain energy and move faster, eventually breaking free from the liquid into gas.

Melting

• Temperature: Increases until the melting point.
• Molecular Movement: Molecules gain energy and move more freely, transitioning from a solid (fixed positions) to a liquid (more movement).

Freezing

• Temperature: Decreases until the freezing point.
• Molecular Movement: Molecules lose energy and slow down, arranging into fixed positions, transitioning from a liquid to a solid.

Sublimation

• Temperature: Generally increases (but can occur at stable temperature).
• Molecular Movement: Molecules gain enough energy to directly escape from solid to gas, bypassing the liquid state, with increased movement.

These changes reflect how temperature affects the energy and movement of molecules in different states of matter!

Answer 2

Answer 3

Sure! Here’s a more simplified version:

Boiling

• Temperature: Rises.
• Molecular Movement: Molecules move faster and escape as gas.

Melting

• Temperature: Rises.
• Molecular Movement: Molecules move more freely, turning solid into liquid.

Freezing

• Temperature: Falls.
• Molecular Movement: Molecules slow down and form a solid.

Sublimation

• Temperature: Can rise or stay the same.
• Molecular Movement: Molecules jump from solid to gas directly.

That’s it!
