## Homework Statement

A scientist heats up a substance by applying heat at a constant rate of 75 J/s. She measures that

it takes 1 minute for 100 grams of the substance to evaporate. What is the latent of vaporization

of this substance? If she starts with 1 kg of the substance, how long will it take for it to

evaporate and how much energy will it take to evaporate the substance?

## Homework Equations

Q=mL?

**3. The Attempt at a Solution [/b**

I'm not really sure how to use Q=mL. Does 75 J/s go into Q or is Q the total amount of joules. I know m is the mass and L is the specific latent heat.
