The bubbles are pockets of steam which is the same chemical as water, just in a different state. As , EL NORTE is a melodrama divided into three acts. Salt, initially is actually just a conglomerate of sodium and chloride ions and by dissociating them, just the arrangement of the ions has changed.

Which of the following is not a physical change? When the chemical bonds of the reactants are broken, sometimes excess energy is released, causing heat to be discharged, and leading to an increase in temperature. Bubbling can be the indication for both chemical or physical change. This motion not only helps to move the water around more quickly (think stirring), but the bubbles themselves transfer heat energy as well.
