Learning objective: I can explain the relationship between temperature and the kinetic energy of particles.

Identify which substance has the most energy. For each pair, enter >, =, < or "need more information" (N.M.I) on the line.
If you marked any pair of substances "need more information", explain why

Thermal Energy

The total energy of a substance (thermal energy) depends on:
the kinetic energy or the speed of the particles (measured by the temperature)
the potential energy or the arrangement of the particles (determined by the state of matter).
the total number of particles in the substance (measured by the mass of the substance), and 
the type of matter that makes up the substance

Thermal energy is the total energy of a system that is dependent on the number of particles in the system, the state of the material, and the temperature. Thermal energy is not the same as temperature. Temperature is the measure of the average kinetic energy of the particles. Molten or liquid metal is the temperature as the metal it is flowing over. However, the liquid metal's particles have more kinetic and potential energy. 

Categorize the following

the speed of the particles
arrangement of the particles
the total number of particles in the substance

Kinetic Energy
Potential Energy
Mass of a substance

A) Complete the model of the particles
B) Indicate how the potential energy is changing (increasing or decreasing).
C) Indicate how the attractive forces are changing (increasing or decreasing).
