Temperature and internal energy.
What do you know about temperature? Please, try to give definition.
The quantity that tells how hot or cold something is compared with a
standard.
Temperature Scales
Freezing point to boiling point of water
* Fahrenheit: 32 to 212, range of 180 degrees.
* Celsius: 0 to 100, range of 100 degrees.
* Kelvin: 273 to 373, range of 100 degrees.
Heat
Heat is the net energy transferred from one object to another because of
a temperature difference.
Internal Energy Includes:
* molecular translation form place to place,
* molecular vibration,
* molecular rotate.
What is difference between heat and temperatures?
Think 2 minutes and give answer.
Temperature
* A measure of hotness or coldness of an object
* Based on average molecular kinetic energy
Heat
* Based on total internal energy of molecules
* Doubling amount at same temperature doubles heat
How do we measure temperature?
Think 2 minutes and give answer
How does the thermometer know how hot the substance is?
Think 2 minutes and give answer
The molecules of the substance bump into the thermometer and transfer
energy. How often and how hard they bump into the thermometer are

913 directly related to their speed. Temperature turns out to be related to the
average speed of the molecules in a substance.
Temperature is not a measure of the total amount of energy in an object.
Thermal Energy = internal energy = a measure of the total kinetic and
potential energy in an object
Ways of changing of internal energy:
Heat transfer
