Question

Which answer best describes the transfer of heat that occurs when 1.20 mol:

a) Conduction
b) Convection
c) Radiation
d) Advection

Answer 1

Heat transfer refers to the movement of energy due to temperature differences and occurs through conduction, which is direct physical contact, convection, involving movement of fluids, and radiation, which is through electromagnetic waves.

Step-by-step explanation:

The question is focused on heat transfer when referring to the movement of energy due to temperature differences. There are three primary methods of heat transfer: conduction, convection, and radiation.

• Conduction is the transfer of heat through stationary matter via physical contact. An example is heat moving from a hot stove to a pan via the metal of the pan.
• Convection involves the transfer of heat by the macroscopic movement of a fluid, such as the air movement within a room or water in a pot being heated.
• Radiation is the transfer of energy by electromagnetic waves. This can be seen when the Sun warms the Earth or when heat radiates from a lightbulb filament.
