Ivi Casagrande
The learning goals for tonight's activity include:
- Be able to describe the behavior of a system of one type of particle as either gaseous, liquid or solid
- Be able to manipulate particle properties and/or the potential energy function for their interaction to change
the 'state' of the particles (gas --> liquid --> solid) without changing particle size or the temperature.
Observe the particles in the simulation below. Describe how the particles behave and whether this behavior
is more like that of a gas, liquid or solid. Explain why using complete sentences with specific details.
The particles behave as being in a gas state. The particles are freely moving and do not get into clusters ( like solid does). There is a lot of kinetic energy between those particles because of their free movement.
Make a change(s) that cause the molecules to behave more like a liquid without changing the particle
diameter or the temperature of the system. Describe with complete sentences and specific details
why the behavior of the system after your changes is more like a liquid.
In order to change the behavior of the particles to make them behave more like a liquid, I increased the minimum potential energy of the system using the graph. Consequently, the particles will have less kinetic energy, and will move less freely compared to the gas state. The particles still have a little bit of kinetic energy but not enough to overcome the potential energy and move freely like in the gaseous state.
Repeat the above for a solid.
In order to achieve a solid state, I did the same as the last one when I had to change to liquid state. I increased even more the minimum potential energy, making the kinetic energy decrease. The less kinetic energy the particles have, the less energy they will have to move. The kinetic energy will be at minimum level, not enough to overcome the potential energy, thats why the particles do not move that much.
