Thermal Energy and Heat

Front

What is thermal energy?

Back

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

Front

What is heat?

Back

Heat is the transfer of thermal energy from one object to another due to a temperature difference.

Front

What is the first law of thermodynamics?

Back

The first law of thermodynamics states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is the second law of thermodynamics?

Back

The second law of thermodynamics states that thermal energy cannot spontaneously flow from a colder body to a hotter body.

Front

What is specific heat?

Back

Specific heat is the amount of heat required to raise the temperature of one kilogram of a substance by one degree Celsius.

Front

What does the formula Q = m x c x ∆T represent?

Back

This formula calculates the heat energy (Q) absorbed or released by a substance, where m is mass, c is specific heat, and ∆T is the change in temperature.

Front

What happens to the kinetic energy of particles as temperature increases?

Back

As temperature increases, the kinetic energy of the particles also increases.

Front

What is conduction?

Back

Conduction is the transfer of heat through a material without the movement of the material itself, typically occurring in solids.

Front

What is convection?

Back

Convection is the transfer of heat by the movement of fluids (liquids or gases) due to differences in density.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation.
