Another heating question

-
How many gallons of boiling water do you think I would need to pour into the pool in order to raise the temperature from 70 degrees to 85?

Well, I think first you would have to take out some of the 70-degree water to make room for the boiling water. And then, the answer to your question would be: a lot.

I think it might be more effort than it was worth, but that is just my guess. It would be better to sneak into a hotel and use their hottub.

That's easy.
H = m_1 c ∆T_1 = m_2 c ∆T_2
m_1 = lots
∆T_1 = 15 degrees F
∆T_2 = 212-70 = 142 degrees F
m_2 = lots/10 (approximately)

So you have to drain about one tenth of the pool and replace it with boiling water.
Now, if you could heat it by pumping steam into the bottom, then that would be different, because you'd have all that heat of vaporization to help.
See, those high school chem problems actually are useful in real life.

Okay, well I guess I will take it back. For serapio, it would be easier to heat the pool. For me, I would still go to a hotel and pretend to be a tourist and use their hottub.

Stone of Help

For the longest time I thought “Ebenezer” was a cup. Not just any cup, mind you, one of those old drinking vessels that might also be called goblet or chalice. My reasoning, you see, was all based on the hymn, “Here I raise mine Ebenezer, hither by thy help I’m come.” To my little girl ears, it sounded like someone was proposing a toast, glass in hand to having made it so far. I know better now, but I still feel as if I am far more likely to toast how far I’ve made it than to set a large stone on end. But truthfully, I’m not very likely to do either. Don’t get me wrong. I’m not slighting the role God has had in bringing me as far as I am. And it’s not a lack of gratitude that turns me into being one of the nine lepers who never returned to thank Jesus for his healing. (At least, not always.) Instead, I’ve found that many times I don’t want to draw attention to what God has done for me because I worry it will make others feel as if I am intimating that I am a favor

The Crazy Market

There is a place here in Beijing that I (not so) affectionately call The Crazy Market. Imagine four floors of wall to wall shops, one shop selling the same thing that 15 other shops are selling, all displayed with bright colors and lights and each shop having two or three people who call out "Hello! What are you looking for?" "Hello! We give you good price!" "Hello! How many coats you want buy?" "Hello! We have your size shoe!" (This one makes me want to stop and say "Oh, I greatly doubt it.") "Hello! Nice pearls for you!" If you so much as look at an item, it is immediately assumed that you will buy it and so they call out "What is your highest price? We give you good discount." The only exception to this is the very bottom floor that is filled with every imaginable and unimagineable sea creature and various sea creature parts in various stages of life. This serves as a good aroma which frequently makes its way up t

The Right Trousers

-
Someone once told me that a friend of theirs received a package from an anonymous person that contained a pair of pants inside. It was mailed from across the country, yet the pair of pants was the right size and style for this particular person. Now I consider that to be a great mystery. But I also consider it a mystery that I wouldn't mind happening to me. Because, you see, playing with children wreaks havoc on my pants. Especially if I have the misfortune to sit down on some unknown substance which then leaves a very unfortunate colored stain in a very, very unfortunate spot. I may have to consider some creative patch work, but that, too, has its problems. I say this because I have another pair of pants that developed a hole the size of Montana near one of the back pockets. (Please do not speculate on the size of the pants based on the size of the hole.) My most beautiful sister, in what I thought was a display of pure magnanimous affection, bought me a couple of patches to fix t
