Solid Liquid Gas
whats is happening the the molecules in this material as it goes from solid to liquid to gas?
they are slowing down because they have less kinetic energy
they are going faster because they have les kinetic energy
they are going faster because they have more kinetic energy
they are going slower because they have more kinetic energy
The correct answer is: they are going faster because they have more kinetic energy.
In the solid state, the molecules are tightly packed and vibrating in fixed positions. As energy is added to the material, such as by increasing the temperature, the molecules gain kinetic energy and begin to move more rapidly. This causes them to overcome the attractive forces between them and transition into the liquid state, where they are more loosely packed and can slide past one another.
Further adding energy causes the molecules to move even faster, eventually breaking free from the attractive forces completely and entering the gaseous state. In the gas phase, the molecules have the most kinetic energy compared to the solid and liquid states, as they are moving freely and independently in all directions.
