2
The Temperature!!!

• A measure of the average kinetic energy of all
  the particles in an object is the temperature.

3
The Speed of Particles!!!

• If a liquid has a high temperature, such as hot
  cocoa, the particles in the liquid are moving
  faster, and have a high average of kinetic energy.

4
The speed of particles part II !!!

• If a drink has a low temperature, such as a
  smoothie, the particles move slower and have a
  lower average of kinetic energy.

5
WHY?

• The particles in a hot liquid move faster because
  the heat gives the liquid extra energy.
• For example If your hands are cold, you could
  add energy to your hands by putting them over a
  hot stove or by a fire. The added energy makes
  the particles in your hands move faster.

6
The Particles in a Doorknob!!!

• Particles in a metal doorknob do not move as fast
  as particles in air. However, the particles in a
  doorknob have more mass and they can have the
  same amount of kinetic energy as particles in air.

7
Particles in a Bowl!!!

• If you set a hot bowl on a table for awhile,
  particles in the bowl will slow down, due to
  collisions with particles in the air and on the
  table. The temperature of the bowl decreases and
  it becomes cooler.

This is the end!!!
