Your friend is asked to differentiate between evaporation and boiling.what questions could you ask to make him to know the difference between evaporation and boiling?physics question.

Answers

Answer:

Boiling is the "rapid vaporization of liquid" when the liquid is heated at the point where the pressure of the vapor is equal to the pressure exerted by the atmosphere in the liquid.

So during the boiling, the vaporization of the water is also occurring but is a little bit more complex.

Some questions that you may ask your friend to differentiate those two phenomena are:

Which one is used to cook things like pasta? (boiling)

in which process, a liquid is transformed into a gas? (evaporation)

Which one includes the other? (boiling)

Final answer:

Evaporation and boiling are both phases changes, but they differ in the specifics of how and when they happen. These differences involve the temperature and location within the liquid where they occur, as well as the speed of the process.

Explanation:

To differentiate between evaporation and boiling, you could ask your friend these questions:

Does the process occur at any temperature or only at a specific temperature (the boiling point)? (Evaporation can occur at any temperature while boiling only occurs at the boiling point.)
Does the process occur throughout the liquid or only at the surface? (Boiling occurs throughout the liquid while evaporation happens only at the surface.)
Is the process slow or fast? (Evaporation is a slow process while boiling is relatively quick.)

By asking these questions, your friend will be able to identify the key differences that separate evaporation from boiling.
