Bill Nye Heat Video Flashcard

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as light or infrared radiation. It does not require a medium to travel through.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. Heat moves from the hotter object to the cooler one.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). Warmer parts of the fluid rise while cooler parts sink, creating a circulation pattern.

Front

True or False: Heat can be found in cold objects.

Back

True. Even cold objects have heat energy, but it is less than that of warmer objects.

Front

What is a conductor?

Back

A conductor is a material that allows heat or electricity to pass through it easily. Metals like copper and aluminum are good conductors.

Front

What is an insulator?

Back

An insulator is a material that does not allow heat or electricity to pass through it easily. Examples include rubber, wood, and plastic.

How does a clothes dryer use forced convection?

Back

A clothes dryer uses forced convection by blowing hot air over wet clothes, which helps to evaporate the moisture quickly.

Front

What is thermal energy?

Back

Thermal energy is the total energy of all the particles in an object due to their motion. It is related to temperature.

Front

What is the difference between heat and temperature?

Back

Heat is the energy transferred between objects due to a temperature difference, while temperature is a measure of the average kinetic energy of the particles in a substance.

What happens to heat when you wear gloves in cold weather?

Back

Wearing gloves helps to reduce heat loss from your hands through conduction, keeping them warm.
