Science
First law of Thermodynamics.
Thermal energy cannot be created nor destroyed, only transferred.
Give two examples of thermometric properties.
Thermal expansion and electrical resistance.
Thermal energy is an object's capacity for heat, while heat is just a qualitative term for warm.
Contact, heat is conducted from one object to another -- water in a pan.
Define radiation and give an example.
No contact, heat is radiated onto something else -- sun, microwave.
Describe convection and give an example.
No contact, heat is brought by another fluid -- wind
Define kinetic energy.
The "motion" energy of an object.
Father of Thermodynamics.
Nicholas Carnile.
Dominion Story
Trying to find a source of renewable thermal energy that is safe, nonpolluting, and economical.
Triple point of water.
273.16 Kelvin
Define thermal energy.
The kinetic "heat" energy of an object.
Describe the Kinetic Molecular Theory.
Everything is made of tiny particles that are constantly in motion.
Four fiduciary points.
Pure water's freezing, boiling, and triple point, along with absolute zero.
What is heat and how is it measured?
Heat is the thermal energy of an object. It's measured by using a substance (e.g. mercury) that expands when heated.
Define internal energy.
Thermal energy.
