2. Energy Transfer: Heat and Temperature
Study Pack #5

3. What do you know? True(A) or False(B)
The particles in matter are always moving
The particles in matter have potential energy
The warmer a substance is, the more energy its particles have
Heat moves from cooler substances to warmer substances
Thermal equilibrium means that both substances have the same temperature

4. Transformation and Transfer
Energy can be transformed or changed into another form
Energy can also be transferred from one object to another
Today we will talk about the transfer of thermal energy

5. Temperature and Kinetic Energy
Any material or object is made up of atoms or molecules
Recall properties of solids, liquids, and gases
The particles in materials are moving constantly

6. Temperature and Kinetic Energy
Because the particles are moving, they have kinetic energy.
Thermal energy is a type of kinetic energy
The faster the particles are moving, the more kinetic energy they have. Or the faster they move, the more thermal energy a substance has.
Which has more kinetic energy?
A. Solid
B. Liquid
C. Gas

7. Temperature and Kinetic Energy
Temperature is the measure of the average kinetic energy of the particles in an object.
When an object’s temperature is higher, its atoms or molecules have more kinetic energy

8. Heat
A transfer of thermal energy from one object to another due to a difference in temperature is called heat.
Heat flows from warmer objects to cooler ones.
Energy always flows from the warmer object to the cooler object
For example, heat flows from a hot cup of coffee to your hand

9. Heat
Heat will continue to flow to the cooler object until the two objects become the same temperature, this is called thermal equilibrium

10. What did you learn? True(A) or False(B)
The particles in matter are always moving
The particles in matter have potential energy
The warmer a substance is, the more energy its particles have
Heat moves from cooler substances to warmer substances
Thermal equilibrium means that both substances have the same temperature
