No, molecular motion actually increases when water is boiling. When water reaches its boiling point, the molecules absorb enough heat energy to break free from the liquid phase and transition into the gaseous phase, leading to increased molecular motion.
No.
Boiling water can be either thermal energy or kinetic energy dependent upon how it's used. If it is used to heat up another object (thereby transferring energy in that manner) it is thermal; if the water vapor from the boiled water is used to say, run a turbine, it would be kinetic in that sense. Chances are, for most cases involving boiling water, or more specifically the water vapor produced by it, the energy associated with that will be kinetic.
Boiling water is physical change.
To boil water successfully, place a pot of water on the stove over high heat. Wait for the water to come to a rolling boil, where bubbles are rapidly rising to the surface and breaking. Once boiling, reduce the heat to maintain a gentle boil as needed for your recipe.
Convection occurs when heat is transferred into an object through motion or movement; an example would be boiling water.
It refers to a boil. When water is boiling, a rolling boil is when you are stirring the water and it is still boiling.
When heat is transferred into an object through movement, such as boiling water, it is known as convection. In this process, heat is transferred through the bulk movement of molecules within a fluid. As the water heats up, the hotter molecules rise to the top, transferring heat from the bottom of the pot to the top.
No, molecular motion actually increases when water is boiling. When water reaches its boiling point, the molecules absorb enough heat energy to break free from the liquid phase and transition into the gaseous phase, leading to increased molecular motion.
When heat is transferred into an object through motion or movement, it is known as convection. In the case of boiling water, the heat is transferred through convection as the heated water at the bottom rises, and the cooler water at the top moves down to replace it, creating a circulating flow of heat.
The correct term is "rolling boil." This describes a continuous agitation of the water as it reaches its boiling point. "Roiling" typically refers to something turbulent or agitated, but not specifically related to boiling water.

No.
A boiling water vortex forms when water is heated to its boiling point and starts to circulate in a swirling motion. This happens because the hot water rises and cooler water moves in to take its place, creating a vortex. The characteristics of a boiling water vortex include a central column of rising steam, a swirling motion of the water, and a relatively stable shape as long as the heat source is maintained.
Signs that water is boiling include bubbles rising to the surface rapidly, steam coming off the surface of the water, and the water appearing to be in a constant motion.
To properly add salt to boiling water, simply sprinkle the desired amount of salt into the water once it has reached a rolling boil. Stir the water to ensure the salt is evenly distributed.
