Heat and Temperature

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.

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.

3. Temperature Scales

• See board for diagram!

II. Big Idea Energy flows from warmer to
cooler objects.

• Energy is transferred from the warmer lemonade
  to the cold ice through 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

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.

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
