Answer:Convection
Explanation:
Convection is the heat transfer procedure by the movement of liquid or gas molecules. It is a combination of diffusion and bulk motion of molecules. Near the surface of the liquid diffusion process dominates while at certain height bulk motion of liquid dominates.
Convection can be
Natural : Natural convection occurs due to density differences
Forced: Force convection occurs when we apply external heat source.
Answer:
Impulse-The effect of force acting over time to change the momentum of an object.
momentum-The product of mass of a particle and its velocity.
