Solution
To answer the question step by step:
-
Understand the relationship between heat energy and temperature:
- Heat energy is the total energy of molecular motion in a substance.
- Temperature is a measure of the average energy of molecular motion in a substance.
-
Analyze each option:
-
Option 1: "As heat energy decreases and temperature remains constant, condensation occurs."
- Condensation typically occurs when a gas loses heat energy and cools down, leading to a phase change from gas to liquid. However, if temperature remains constant, it implies no phase change is happening.
-
Option 2: "As heat energy increases and temperature increases, freezing occurs."
- Freezing is the process of a liquid turning into a solid, which usually happens when heat energy is removed and temperature decreases, not increases.
-
Option 3: "As heat energy decreases and temperature remains constant, evaporation occurs."
- Evaporation is the process of a liquid turning into a gas, which typically requires an increase in heat energy. If temperature remains constant, evaporation is unlikely to occur.
-
Option 4: "As heat energy increases and temperature decreases, melting occurs."
- Melting is the process of a solid turning into a liquid, which requires an increase in heat energy. However, temperature should increase, not decrease, for melting to occur.

- None of the provided options correctly explain the relationship between heat energy and temperature in the context of phase changes.
-
Conclusion:
- The correct relationship is not accurately described by any of the given options.
