Temperature, Thermal Energy and Heat Transfer- WVMS

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of all the particles in an object, which is related to its temperature.

Front

True or False: The more particles (mass) an object has at a given temperature, the more thermal energy it has.

Back

True

Front

What is the Fahrenheit scale?

Back

The Fahrenheit scale is a temperature scale where water freezes at 32 degrees and boils at 212 degrees, commonly used in the United States.

Front

What is the Celsius scale?

Back

The Celsius scale is a temperature scale where water freezes at 0 degrees and boils at 100 degrees, commonly used worldwide.

Front

What is heat transfer by conduction?

Back

Heat transfer by conduction occurs when two objects are touching and heat moves from the hotter object to the cooler one.

Front

What is heat transfer by convection?

Back

Heat transfer by convection occurs through the circulation of a fluid, where hot fluid rises and cold fluid sinks, creating a current.

Front

What is heat transfer by radiation?

Back

Heat transfer by radiation happens when heat travels through space in waves outwardly in all directions.

Front

What is the relationship between temperature and thermal energy?

Back

As the temperature of an object increases, its thermal energy also increases due to the increased motion of its particles.

Front

What happens to thermal energy when ice melts?

Back

When ice melts, thermal energy is absorbed, causing the solid ice to change into liquid water.

Front

What is the boiling point of water in Celsius?

Back

The boiling point of water in Celsius is 100 degrees.
