What is heat?
What is the natural flow of heat?
Heat flows spontaneously from hot objects to cold objects.
How many laws are there in thermodynamics?
There are 3 laws.
What are the two main types of heat engines?
The two main types of heat engines are the external combustion engine and the internal combustion engine.
What is my favorite animal?
Bunny
The transfer of energy by waves moving through space.
What is Radiation?
When does thermal expansion occur?
Thermal expansion occurs when particles of matter move farther apart as temperature increases.
How does an object's temperature affect radiation?
As an object's temperature increases, the rate at which it radiates energy increases.
How do most heating systems distribute thermal energy?
Most heating systems use convection to distribute thermal energy.
What is the name of Emaleigh's green dinosaur?
Richard
The study of conversions between thermal energy and other forms of energy.
What is Thermodynamics?
What two variables is thermal energy related to?
Thermal energy is the total potential and kinetic energy of all the particles in an object, therefore having relations to potential and kinetic energy.
Why is conduction slower in gases than in liquids or solids?
Conduction in gases is slower than in liquids and solids because the particles in a gas collide less often.
What are the most commonly used energy sources for central heating systems?
The most commonly used energy sources for central heating systems are electrical energy, natural gas, oil, and coal.

What is an Internal Combustion Engine?
What is the formula for specific heat?
Q = m x c x △T
Which law of thermodynamics states that thermal energy can flow from colder objects to hotter objects (only if work is done on the system)?
The second law of thermodynamics.
What happens when a refrigerant absorbs heat?
It vaporizes, and turns into a gas.
How many My Little Pony episodes are there for G4?

Are all metals good thermal insulators?
No; they are good conductors.
How is a room heated by an electric baseboard heating system?
Convection and radiation only.
