Convection in terms of particles refers to the transfer of heat through the movement of particles in a fluid (liquid or gas). As the fluid is heated, the particles gain energy and move faster, becoming less dense and rising, while cooler, denser particles sink. This creates a circulating flow that helps distribute heat throughout the fluid.
What else can I help you with?
How does the process of diffusion differ from convection in terms of the movement of particles?
Diffusion involves the movement of particles from an area of high concentration to an area of low concentration, while convection involves the transfer of heat through the movement of a fluid. In diffusion, particles move randomly, while in convection, particles move in a specific direction due to the flow of the fluid.
What are the differences between diffusion and convection in terms of the movement of particles in a fluid medium?
Diffusion is the movement of particles from an area of high concentration to an area of low concentration, while convection involves the transfer of heat through the movement of the fluid itself. In diffusion, particles move randomly, while in convection, the fluid moves in a specific direction due to temperature differences.
What are the differences between convection and radiation in terms of heat transfer mechanisms?
Convection and radiation are two different ways heat is transferred. Convection involves the movement of heated particles in a fluid, like air or water, while radiation is the transfer of heat through electromagnetic waves. Convection requires a medium to transfer heat, while radiation can occur through a vacuum.
Does radiation and convection need particles of matter?
No, radiation does not require particles of matter as it can travel through a vacuum. Convection, on the other hand, does involve the transfer of heat through the actual movement of particles, such as in a gas or liquid.
What is the transfer of energy by the motion of heated particles in a gas or liquid?
This transfer of heat is called convection.

Transfer of energy by movement of particles is?
Convection is the movement of particles due to a gradient of energy. Heat energy is thus transfered by the moving particles.
What heat transfers fast particles colliding with slower particles?

What of the three states of matter do particles transfer significant amounts of heat energy by both conduction and convection?
Particles in liquids transfer significant amounts of heat energy by both conduction and convection. Conduction occurs as heat is transferred through direct contact between particles, while convection is the process of heat transfer through the movement of particles within the liquid.
What is the transfer of energy by the motion of heated particles in fluid?
