Question

which process is responsible for the movement of heat in boiling water?
conduction
radiation
insulation
convection

Explanation:

Conduction is the transfer of heat through direct contact. Radiation is the transfer of heat via electromagnetic waves. Insulation is a material that reduces heat transfer. Convection is the transfer of heat through the movement of fluids (liquids or gases). Boiling water involves the movement of water (a liquid), which is a fluid. In boiling water, the warmer (less dense) water rises and the cooler (more dense) water sinks, creating a circular motion. This circular motion of the fluid (water) is characteristic of convection.

Answer:

Convection
