Question

Predict the energy trend as a substance changes from a solid to liquid to gas on this graph.

A) It would increase from bottom left to top right.
B) It would decrease from top left to bottom right.
C) It would be a horizontal line as energy would remain constant.
D) It would increase from solid to liquid, then decrease from liquid to gas.

Answer 1

A) It would increase from bottom left to top right.

Step-by-step explanation:

The energy that can be found in matter, is the energy of the particles moving inside it, so as you know in a solid state the particles move slower and are almost set still in a single spot, so the energy will increase as the substance goes from solid, to liquid to gas, because the energy in the particles will increase.

Answer 2

Answer:
Option-A ( It would increase from bottom left to top right) is the correct answer.

Step-by-step explanation:
As we know converting solids into liquids and converting liquids into gases require energy. This energy provided increases the energy of the state and its particles start moving with higher velocities. Therefore, the energy of solids will be lower than liquids and gases respectively. While, liquids have greater energy than solids but less energy than gases. And, gases are the most energetic than solids and liquids.
