Energy Transfer and Temperature

Front

What is thermal energy?

Back

The TOTAL energy of all its moving particles.

Front

What is the dependent variable in an experiment?

Back

The variable that changes in response to the independent variable; it can also be referred to as the effect.

Front

What are the three temperature scales?

Back

Fahrenheit, Celsius, and Kelvin.

Front

What is unique about the Kelvin temperature scale?

Back

It is not measured in degrees.

Front

Can the environment affect energy transfer?

Back

Yes, the environment can affect how energy transfers.

Front

How does the material of an object affect thermal energy?

Back

The material of an object DOES have an effect on thermal energy.

Front

What is energy transfer?

Back

The movement of energy from one object or system to another.

Front

What is the difference between conduction, convection, and radiation?

Back

Conduction is energy transfer through direct contact, convection is transfer through fluid movement, and radiation is transfer through electromagnetic waves.

Front

What is the role of temperature in energy transfer?

Back

Temperature measures the average kinetic energy of particles; higher temperatures generally lead to faster energy transfer.

Front

What happens to thermal energy when ice melts?

Back

Thermal energy is absorbed by the ice, causing it to change from solid to liquid.
