Heat Transfer
100

This law states that absolute zero cannot be reached.

3rd law

100

The study of conversions between thermal energy and other forms of energy.

thermodynamics

100

a measure of how hot or cold an object is compared to a reference point.

temperature

100

Heat flows spontaneously from _________ to _______.

hot to cold

100

The transfer of thermal energy with no net transfer of matter.

conduction

200

This law states that energy is conserved.

1st law

200

Thermal energy that is not converted into work.

waste heat

200

______ is related to the average kinetic energy of the particles in an object due to their random motions through space.

temperature

200

________ is defined as a temperature of 0 kelvins.

absolute zero

200
The transfer of energy by waves moving through space.

radiation

300

A consequence of this law is that the efficiency of a heat engine is always less than 100 percent.

2nd law

300
The amount of heat needed to raise the temperature of one gram of material by one degree Celsius.

Specific heat

300

________ is dependent on the mass, temperature, and phase of an object.

thermal energy

300

_________ created the ice cream churn.

Nancy Johnson

300

The transfer of thermal energy when particles of a fluid move from one place to another.

convection

400
This law states that thermal energy can flow from colder objects to hotter objects only if work is done on the system.

2nd law

400

The increase in the volume of a material due to a temperature increase.

thermal expansion

400

The transfer of thermal energy from one object to another because of temperature difference.

heat

400

In _________ the ice cream machine was patented.

1843

400

True or false. In most solids, conduction takes place as particles vibrate in place.

True

500

An instrument used to measure changes in thermal energy.

calorimeter

500

Copper is a type of thermal __________.

conductor

500

True or False. Matter can be cooled to absolute zero.

false
