Aman consumes 2245 kcal of food in one day, converting most of it to maintain body temperature. if he loses half this energy by evaporating water (through breathing and sweating), how many kilograms of water evaporate?

2.079 kg

Explanation:

Latent heat of vaporisation of water, L = 2,260 kJ/kg = 2260000 J/kg

Energy intake = 2245 Kcal

Energy used for evaporating water = half of energy intake

E = 2245 / 2 = 1122.5 kcal

now convert kcal into Joule

1 kcal = 4186 J

So, E = 1122.5 x 4186 = 4698785 J

let m be the mass of water which is evaporated.

by the use of formula of heat

E = m x L

Where, L be the latent heat of vaporisation.

4698785 = m x 2260000

m = 2.079 kg

i dont think you are wrong for wanting to get even with someone who did you wrong.

(i'm an eye for an eye kind of person) but if this person hurt you in a sexual way, i dont suggest doing anything to him. he should be taken to the proper authorities, you could go to jail depending on what you do. if it was something small like your sibling took your spot on the couch, than yea, i would get even with him by taking one of his favorite snacks lol. but i dont suggest you doing anything illegal.
