Conduction Convection and Radiation

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

Convection is the transfer of heat through the movement of fluids (liquids and gases) caused by differences in temperature and density.

Radiation is the transfer of heat in the form of electromagnetic waves, such as light, and does not require a medium to travel.

Heat moves from warmer to cooler areas.

When molecules are heated, they gain energy, move faster, and become less dense.

They cool down, become more dense, and sink.

Chloroplasts capture sunlight to perform photosynthesis, converting light energy into chemical energy.

Mitochondria are known as the powerhouse of the cell, where energy is created in the form of ATP.

Conduction occurs in solids without movement of the material, while convection involves the movement of fluids.

Thermal equilibrium is the state in which two objects in contact do not exchange heat, meaning they are at the same temperature.
