1. Heat and Temperature

2. Big Idea: Temperature Depends on Particle Movement
Solid Liquid Gas

3. 1. Temperature
• All particles in matter have kinetic energy, or the energy of movement.
Temperature is the measurement of the kinetic energy (or motion) of particles

4. 1. Temperature
Temperature can be measured on the Fahrenheit, Celsius, or Kelvin scales.

5. 1. Temperature
Particles in a warmer substance have a greater average kinetic energy than particles in a cooler substance.
hot liquid
cold liquid

6. 2. Kinetic Theory Of Matter
The energy of motion. A moving object has the most kinetic energy at the point where it moves the fastest.

7. 3. Temperature Scales
See board for diagram!

8. II. Big Idea: Energy flows from warmer to cooler objects.
Energy is transferred from the warmer lemonade to the cold ice through heat.
ice
heat

9. HEAT
The flow of energy from an object at a higher temperature to an object at a lower temperature.
2. Energy that is transferred from a warmer object to a cooler object.

10. Thermal Energy
The energy an object has due to the motion of its particles; the total amount of kinetic energy of particles in an object

11. 3. Methods of Heat Transfer
Conduction
Conduction occurs in solids only.
Conduction is the transfer of heat energy
from atom to atom by physical contact

12. 3. Methods of Heat Transfer
Convection
Convection occurs in liquids and gases.
Convection is the transfer of heat energy by the movement of the atoms themselves

13. 3. Methods of Heat Transfer
Radiation
Radiation is heat transfer with no atoms.
Transfer of heat energy through waves.

14. Heat Transfer

15. Conductors
A material that transfers heat and electrical energy easily.
Examples
silver
copper
gold
aluminum
iron
steel

16. Insulators
1. A material that does not transfer heat or electrical energy easily.
Examples
glass
rubber
oil
porcelain
ceramic
quartz
plastic
