Question

What is the relationship between the internal energy of a substance and its state of matter? A) As a gas loses internal energy it becomes a plasma. Eliminate B) Closer packed atoms generally have more internal energy. C) As the internal energy decreases a substance will spread further apart. D) As the internal energy increases a substance would go from solid to a liquid.

Answer 1

D. As the internal energy increases a substance would go from solid to a liquid.

hope this helps :)

Answer 2

Answer: Option (D) is the correct answer.

Step-by-step explanation:

Internal energy is defined as the minimum amount of energy present within the molecules of a substance.

More is the internal energy within the molecules of a substance more will be the number of collisions between them.

As a results, the particles will move away from each other and this leads to change in state of matter from solid to liquid and liquid to gaseous state.

Thus, we can conclude that the relationship between the internal energy of a substance and its state of matter is that as the internal energy increases a substance would go from solid to a liquid.
