ENERGY CHANGES
Study the image to the left - it shows a dam and reservoir which is used to generate electricity cleanly.
In this case gravitational potential energy is converted to kinetic energy in water in the pipes - which then turns the turbines connected to electrical generators which convert the kinetic energy to electrical energy.

Three States
Describe the arrangement and motion of the particles in each of the three states of matter shown here
fixed pattern, strong forces of attraction, vibrate, keeps its own shape
particles touch, weak intermolecular forces, can take the shape of their container
particles can move freely, very weak intermolecular forces,move randomly,expand to fill the shape of the container
Feeling the pressure?
This simulation can be used to investigate the relationship between the pressure, temperature and volume of a gas.
Use the simulation to help answer the following questions:
1. If you keep the volume constant . How does the pressure change when you change the temperature. In your answer describe what happens to the motion of the particles.
2. What can you say about the pressure created if you select the small volume an the maximum temperature.
3. What settings give the lowest pressure? Explain in terms of the motion of the particles.
