Question

The chemicals begin to effervesce. Effervesces means:

1) To boil
2) To evaporate
3) To fizz or bubble
4) To solidify

Answer 1

3 to fizz

Explanation: effervescence is when gas bubbles are observed

Answer 2

Effervesces means to fizz or bubble, as seen when a liquid containing dissolved gases like carbon dioxide releases these gases in the form of bubbles. This process is distinct from other processes such as boiling or solidifying.

Step-by-step explanation:

The term effervesce refers to the action of a liquid when it produces bubbles of gas and appears to fizz or foam. This usually happens when the liquid contains dissolved gases like carbon dioxide, which is the case with carbonated water that fizzes when the pressure is released. This process of fizzing or bubbling is quite different from boiling, which occurs when a liquid reaches its boiling point and turns into vapor; or evaporation, which is the process where liquid turns into gas at temperatures below its boiling point. Effervescing is not to be confused with solidifying, which is the process of becoming solid. An example of a chemical reaction that causes effervescence is the reaction between acetic acid and potassium carbonate, producing carbon dioxide gas bubbles.
