Use the graph and diagram to answer the question.
The vertical axis is labeled, temperature (degrees C), and ranges from a point below 0 to 100 degrees C. The horizontal axis is labeled, time of heating. The graph shows a line that starts from the origin and slopes upward as the ice heats up until 0 degrees C. The line becomes parallel to the horizontal axis for some time as the ice melts and gets converted to water. The line starts sloping upward again as the water heats up to 100 degrees C. The line again becomes parallel to the horizontal axis as the water boils into steam.

The phase with the least kinetic energy for the particles in the substance is gas, followed by liquid, and then solid.
The correct answer is:
Least: gas
↓
liquid
Greatest: solid
To rank the phases of matter based on the kinetic energy of the particles in the substance, we need to understand that the kinetic energy of particles increases as the phase changes from gas to liquid to solid.
In the gas phase, the particles are highly energetic and have the highest kinetic energy. They move freely and rapidly, colliding with each other and the walls of their container.
In the liquid phase, the particles have lower kinetic energy compared to gases. They have more intermolecular forces that hold them together and restrict their movement to some extent.
In the solid phase, the particles have the least kinetic energy. They are tightly packed and have very limited movement, vibrating in a fixed position.
Thus, the ranking from the phase with the least kinetic energy to the greatest kinetic energy is: gas, liquid, solid.
