A(n) ________ is a substance that is used to absorb heat.
convection
When ________ occurs, more energetic particles move from one place to another.
radiator
A(n) ________ is a closed metal container that contains hot water or steam.
Thermodynamics
________: Study of the relationship among thermal, energy, and heat.
passive solar
In a(n) ________ heating system, radiant energy from the Sun is transferred to the room through windows.
Temperature
________: a measure of the average kinetic energy of the particles in the object.
source of energy
All heating systems require some ________.
constant motion
Conduction occurs because particles in matter are in ________.
Insulator
________: A material in which heat flows slowly.
Convection currents
________ transfer heat from warmer to cooler parts of the fluid.
thermal energy
If the temperature doesnt change, the ________ in an object increases if the mass of the object increases.
heat pump
A(n) ________ is a two- way heat mover.
Radiation
________: the transfer of energy by electromagnetic waves.
Convection
________: the transfer of thermal energy in a fluid by the movement of warmer and cooler fluid from place to place.
thermal energy
In fluids, ________ can be transferred by convection.
Thermal Energy
The sum of the kinetic and potential energy of all the particles in an object
Heat
thermal energy that flows from something at a higher temperature to something at a lower temperature
Specific Heat
he amount of heat that is needed to raise the temperature of 1 kg of some material by 1°C
Conduction
the transfer of thermal energy by collisions between particles in matter
Convection
the transfer of thermal energy in a fluid by the movement of warmer and cooler fluid from place to place
Radiation
the transfer of energy by electromagnetic waves
Solar Collectors
absorbs radiant energy from the Sun
Thermodynamics
Study of the relationship among thermal, energy, and heat
First Law of Thermodynamics
the increase in thermal energy of a system equals the work done on the system plus the heat transferred to the system
Second Law of Thermodynamics
It is impossible for heat to flow from a cool object to a warmer object unless work is done
Heat Engine
A device that converts heat into work
Internal Combustion Engine
The heat engine in a car
