How much energy would be absorbed or released by the h2o in the process 30 grams h2o(
g. at 100◦c → 30 grams h2o(ℓ) at 20◦c ?

Explanation:

In this case we have two processes. First, we have to convert the gas water into liquid water at 100 ºC and then we have to go from 100 ºC to 20 ºC  in the liquid state.

For the first part, we have to use the enthalpy of vaporization (), so:

In this case we go from gas to liquid, so energy is released, therefore:

In the second part we have to calculate the energy in the change from 100 ºC to 20 ºC, so:

ΔT

So, in total we will have:

to be fair, you have to have a very high iq to understand rick and morty. the humour is extremely subtle, and without a solid grasp of theoretical physics most of the jokes will go over a typical viewer's head. there's also rick's nihilistic outlook, which is deftly woven into his characterisation- his personal philosophy draws heavily from narodnaya volya literature, for instance. the fans understand this stuff; they have the intellectual capacity to truly appreciate the depths of these jokes, to realise that they're not just funny- they say something deep about life. as a consequence people who dislike rick & morty truly are idiots- of course they wouldn't appreciate, for instance, the humour in rick's existential catchphrase "wubba lubba dub dub," which itself is a cryptic reference to turgenev's russian epic fathers and sons. i'm smirking right now just imagining one of those addlepated simpletons scratching their heads in confusion as dan harmon's genius wit unfolds itself on their television screens. what fools.. how i pity them.

and yes, by the way, i do have a rick & morty tattoo. and no, you cannot see it. it's for the ladies' eyes only- and even then they have to demonstrate that they're within 5 iq points of my own (preferably lower) beforehand. nothin personnel kid
