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.

The "No I" Phone

It's a cheap party trick: I pull out my phone, flip it open to check the time or send a quick text, and watch for the reactions. In the decades I've owned a flip phone, people have given me a few double takes. Recently, though, when I opened my phone to squint at a photo texted to me, the person sitting across the conference table surprised me with a "Haha! I love your phone!" And I did, too. I loved my flip phone. Then, in a deadly mistake of distracted domesticity, I scooped it up with my bed sheets and dropped it in the washing machine: Eco Cold, extra spin. Oh gentle readers, the tragedy of beautiful T9 predictive text programming drowned at the bottom of the linens spin cycle! Yes, I lost saved phone numbers, the blurry store photos I'd snapped over the years to double check prices when back to internet access, the text threads with details about addresses and meet-ups... all lost. Sad, inconvenient, annoying, frustrating, all of it. But the biggest tragedy, ...

Amtrak Adventuring

Trying to see it all, 2011 I may never look down the aisle of an Amtrak train without remembering a baby bouncing, holding fast to the seat as the train rocked and bounced even faster. All the world over, trains carry a reputation for efficiency and frugality. That has never been my experience with Amtrak.  The Adventure Begins, June 22, 2011 Thirteen years ago (almost to the day) our little family set out on our first Amtrak adventure. We thought three weeks touring the United States on a train with an infant made so much more sense than the alternative. The alternative being flying or driving (with the same infant) to a wedding in the middle of Cornfieldville, Ohio. Being young and foolish, it made perfect sense. Our baby did not yet sleep through the night, so sitting up in coach seating night after night wouldn't affect our sleep all that much. With a rolling ice chest filled with lunch sacks that prevented us from knowing in advance whether our meal was Option A, B, or C, w...

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...
