Heat is energy that causes particles to move faster and farther apart. As particles move faster, they leave one phase and enter another. Use the diagram below, the dots represent the position of the particles in a substance. What phase change is represented by the BLUE ARROW AT LETTER C?



A

Melting

B

Sublimation

C

Condensation

D

Deposition

Answer 1

To determine the phase change represented by the blue arrow at letter C, let's define the common phase changes:

• Melting: The transition from solid to liquid.
• Sublimation: The transition from solid directly to gas.
• Condensation: The transition from gas to liquid.
• Deposition: The transition from gas directly to solid.

Based on your question, if the blue arrow at letter C indicates that the particles are moving closer together (which happens when a gas cools and transitions to a liquid), then the phase change represented would be C. Condensation.

If you have a diagram or any further details, please provide them for a more accurate assessment. However, based on the typical definitions, the answer is likely C. Condensation.
