Chapter 16 Thermal energy and Heat
What is similar to the average kinetic energy of the particles
Joules, Calories, Kelvins, Celsius
Units of temperature:
They collide frequently
It takes longer for conduction to go through liquids because...
Increase in volume and heat
Thermal expansion is...
In what way is heat transfered from the sun?
The heat = Mass x Specific heat x Change in temp
Q = M x C x (triangle)T
Conducts thermal energy well ( a wire rack in a hot oven / pots and pans)
Conducts thermal energy poorly (air / a double-pane window)
Energy is conserved always
First law of Thermodynamics
Colder objects to hotter objects only work if work is done on the system
Second law of Thermodynamics
Absolute zero cannot be reached
Third law of Thermodynamics
An instrument used to measure changes in thermal energy
A temperature of zero Kelvins
A device that reverses the normal flow of thermal energy
