Thermal Energy- Kinetic TheoryThermodynamics is the study of

Kinetic-molecular theory states

According to Kinetic -Molecular theory, a hot body would have ________________thermal energy. Explain.

• .

Thermal Equilibrium means

How would two objects get to thermal equilibrium?

Temperature and Temp. ScalesThermometer is used to? Explain.

The Celsius scale and water?

Kelvin scale?

Fahrenheit Scale?

Heat Energy and Transfer

Heat travels from?

Heat is is it’s symbol and are its Units.

Heat can be transferred from one object to another through three different process. They are

Conduction-

Convection-

Radiation-

Specific Heat and CalorimetryWhen heat flows into an object, its thermal energy increases. What

about Temperature? Explain.

Calorimetry

Change of State and Calorimetry

Change of State requires?

Vaporization

Fusion

Calorimetry with phase changes? Explain
