- temperature
- is the measure of average kinetic energy of the particles in a moving object
- passive solar heating system
- doesn't have moving parts
- heat
- thermal energy transferred between objects that are different temperature
- states of matter
- forms of matter such as solids, liquids, gases
- thermal pollution
- The excessive heating of a body of water
- thermal energy
- the total kinetic energy of particles that make up a substance
- convection
- the transfer of thermal energy by the movement of a liquids or gas
- calorie
- the amount of heat energy required to raise the temperature of 1 gram of liquid water by 1 degree C'
- thermal conductors
- a material through which energy can be transferred into heat
- active solar heating system
- has moving parts
- thermal insulator
- a material that prevents or reduces the transfer of heat.
- compression stroke
- the crankshaft turns and pushes the piston up, compressing the fuel mixture
- absolute zero
- the temperature which all molecular motion stops
- intake stroke
- a mixture of gasoline and air enters a cylinder as the piston moves down
- thermal conduction
- the transfer of thermal energy from on substance to another in direct contact.
- insulation
- A substance that reduces the transfer of thermal energy
- thermal expansion
- the increase in volume of an object because of the increase in temperature
- power stroke
- spark plug uses electrical energy to ignite the compressed mixture
- compressor
- a mechanical device that compresses gasses
- Thermal conductivity
- is the rate at which a substance transfers thermal energy
- exhaust stroke
- crankshaft turns, and the piston is forced back up pushing exhaust gas out of the cylinder
- radiation
- the transfer of energy as electromagnetic waves
- change of state
- physical change of a substance from one state to another
- specific heat
- The amount of energy required to raise the temperature of 1 gram of a substance by 1*C
- heat engine
- A machine that uses heat to do the work
- refrigerant
- causing cooling or freezing
