Solution
The correct answer is A. Energy is transferred through moving currents of warmer air or liquid. This is the definition of heat transfer by convection. It occurs when heat energy is carried away by the movement of a fluid, such as air or water. This is different from conduction (option C), where heat is transferred through direct contact of molecules, and radiation (option D), where heat is transferred through electromagnetic waves. Option B is not a typical method of heat transfer.

Which statement correctly describes how the transfer of heat energy (thermal energy) between the particles of a substance occurs?ResponsesThermal energy transfers from particles that have a high amount of thermal energy to particles that have a high amount of thermal energy. Thermal energy transfers from particles that have a high amount of thermal energy to particles that have a high amount of thermal energy. Thermal energy transfers from particles that have a low amount of thermal energy to particles that have a low amount of thermal energy. Thermal energy transfers from particles that have a low amount of thermal energy to particles that have a low amount of thermal energy. Thermal energy transfers from particles that have a lower amount of thermal energy to particles that have a higher amount of thermal energy. Thermal energy transfers from particles that have a lower amount of thermal energy to particles that have a higher amount of thermal energy. Thermal energy can't be transferred between particles of matter due to the Law of Conservation of Energy. Thermal energy can't be transferred between particles of matter due to the Law of Conservation of Energy. Thermal energy transfers from particles that have a higher amount of thermal energy to particles that have a lower amount of thermal energy.
