Heat Transfer

Chapter 16

Section 2

By:Krystal Jacobs

• How is temperature measured?
• In what three ways is heat transferred?
Vocabulary
• Thermal Energy:The total energy of motion of energy in the molecules of a substance.
• Thermometer:A thin glass tube with a bulb on one end that contains a liquid, usually mercury or colored alcohol.
• Temperature:The average amount of energy of motion of each molecule of a substance.
• Heat:The energy transferred from a hotter object one .
• Conduction:The direct transfer of heat from one substance to another substance that is touching.
• Convection:The transfer of heat by the movement of fluid.
Energy and Temperature

Thermal Energy:The total energy of motion of energy in the molecules of a substance.

• Temperature: The average amount of energy of motion of each molecule of a substance
Measuring Temperature
• Temperature is measured in units called Celsius or Fahrenheit by a thermometer.
• Thermometer:A thin glass tube with a bulb on one end that contains a liquid, usually mercury or colored alcohol.
• The liquid inside the thermometer expands and contrasts so doing that we are able to tell the temperature.

### The three types of heat!

Convection, and

Conduction.

How Heat is Transferred
• Heat:The energy transferred from a hotter object one .
• Conduction:The direct transfer of heat from one substance to another substance that is touching.
• Convection:The transfer of heat by the movement of fluid.
• What is temperature?
• Describe how a thermometer work.
• Name three ways that heat is transferred.
