|
|
Conduction |
the transfer of thermal energy by collisions between the particles that make up matter |
|
|
Second Law of Thermodynamics |
energy spontaneously spreads from regions of higher concentration to regions of lower concentrarion |
|
|
Solar Collector |
a device that transforms radiant energy from the sun into thermal energy |
|
|
Internal Combustion Engine |
a heat engine that burns a fuel inside a set of cylinders |
|
|
Heat |
energy that is transferred between two objects due to temperature difference |
|
|
Calorimeter |
an instrument used to determine the specific heat of a material or object |
|
|
Coolant |
a substance that can absorb a great amount of thermal energy with little change in temperature |
|
|
Convection |
the transfer of thermal energy in a fluid by movements of warmer and cooler fluid |
|
|
Heat Pump |
a two-way air conditioner |
|
|
Heat Engine |
a device that converts some thermal energy to mechanical energy |
|
|
Thermal Conductor |
a material that is a good conductor of thermal energy (heat) |
|
|
First Law of Thermodynamics |
if the mechanical energy of a system is constant, the increase in thermal energy of that system equals the sum of the thermal energy transfers into the system and the work done of that system |
|
|
Convection Currents |
the rising and sinking action of a fluid that transfers thermal energy from warmer to cooler parts of the fluid |
|
|
Thermodynamics |
the study of the relationships between thermal energy, heat, and work |
|
|
Thermal Energy |
the sum of the kinetic energy and the potential energy of all of the particles that make up an object |
|
|
Thermal Insulator |
a material through which thermal energy moves slowly |
|
|
Thermal Energy Equation |
Q=m(Tf-T)C or Q=mC^T |
|
|
Specific Heat |
the amount of heat needed to raise the temperature of 1 kg of that material by 1degree Celcius |
|
|
Radiation |
the transfer of energy by electromagnetic waves, such as light and microwaves |
|
|
Active Solar Heating |
a type of solar heating system in which a solar collector transforms radiant energy from the sun into thermal energy; a pump circulates the thermal energy through the building |
|
|
Radiator Heating System |
a type of heating system that consists of a closed metal container that contains hot water or steam; a system of pipes carries the hot water or steam to radiators in different rooms |
|
|
Passive Solar Heating |
a type of solar heating system in which materials inside a building absorb radiant energy from the sun and heat up during the day; thermal energy is released by these materials at night |
|
|
Electric Heating System |
a type of heating system in which electric heating coils transform electrical energy into thermal energy |
|
|
Forced-Air Heating System |
a type of heating system in which a furnace burns fuel and heats a volume of air; a fan blows the warmed air through a series of ducts |
|
|
Solar Heating System |
a type of heating system in which radiant energy from the sun is collected and transformed into thermal energy |
