Question

The latent heat of vaporization of a substance is the amount of energy associated with doing which of the following to 1 kg of the substance?

(PLEASE HELP NEED ANSWER ASAP!!)

Answer 1

Converting it from liquid to gas

Answer 2

B) Boiling it at its boiling point

Step-by-step explanation:

As we know that the heat required to convert the given substance from liquid to vapor at its boiling point is known as latent heat of vaporization

So here we know that

`Q = mL`

here we know that

`L = (Q)/(m)`

so it is known as the heat required to boil the given substance of unit mass at its boiling point

so correct answer will be

B) Boiling it at its boiling point
