Thermal Energy 1
What is convection?
Thermal energy transfer via movement of fluid (liquid or gas)
How does heat travel?
From HOT to COLD
What is thermal energy?
the TOTAL amount of kinetic energy in the particles of a substance
What kind of kinetic energy does a cold cup of coffee have?
Less kinetic energy than a hot cup of coffee
What is radiation?
Thermal energy transfer via electromagnetic waves
What is kinetic energy?
Energy of motion
What is conduction?
Thermal energy transfer via direct contact
What occurs as the kinetic energy of the particles INCREASE?
The molecules are moving faster and the temperature increases
