Top 10 Commonly Confused Words in Thermal Physics

Top 10 Commonly Confused Words in Thermal Physics 1. Temperature vs. Heat The terms 'temperature' and 'heat' are often used interchangeably, but they have distinct meanings. Temperature refers to the measure of the average kinetic energy of particles in a substance, while heat is the transfer of energy between objects due to a temperature difference. So, temperature is about the intensity of the energy, while heat is about the transfer of that energy. 2. Conduction vs. Convection When it comes to heat transfer, 'conduction' and 'convection' are frequently confused. Conduction is the transfer of heat through direct contact between particles, like when you touch a hot pan. On the other hand, convection involves the movement of a fluid, such as air or water, to transfer heat. So, conduction is more about direct contact, while convection involves the movement of a substance. 3. Thermal Equilibrium vs. Thermal Equilibration While these terms sound similar, they have different meanings. Thermal equilibrium refers to a state where two objects are at the same temperature and no heat flows between them. On the other hand, thermal equilibration is the process by which two objects in contact eventually reach thermal equilibrium. So, equilibrium is the state, while equilibration is the process of reaching that state. 4. Internal Energy vs. Heat
