steam tables n such?

Question

anybody know the specific heat capacity of water at 100C? Y'know, right before the Hv is overcome and it turns to steam? I know it's 4.184 at 25C... raaawr, I'd kill for something more than my steam tables...

Answer 1

Since water can be considered incompressible (unlike say air), there are some interesting properties that allow cp=cv and we can simply write specific heat as c.

So we can approximate the value at 100C using nearby values.
H2O at T1=76.85 has c1=4.195
at T2=101.9 has c2=4.220
So we interpolate:

c=[(T1-T2)/(c1-c2)]*(100-T1)+c1

c= 4.218

Bartender Is Sitting Behind The Bar On A Typical Day A bartender is sitting behind the bar on a typical day, when the door bursts open and in come four exuberant blondes. They come up to the bar, order five bottles of champagne and ten glasses, take their order over and sit down at a large table. The corks are popped, the glasses filled and they begin toasting and chanting, "51 days, 51 days, 51 days." Finally, the tenth and final blonde arrives with a picture under her arm. She walks over to the table, sets a picture in the middle and the table erupts. Up jump the others and they begin dancing around the table, exchanging high-fives while chanting, "51 days, 51 days, 51 days." The bartender can't contain his curiosity any longer, so he walks over to the table. There in the center is a beautifully framed child's puzzle of the Cookie Monster. When the frenzy dies down a little, the bartender asks one of the blondes, "What's all the chanting and celebration about?" The blonde who brought in the picture pipes in, "Everyone thinks that blondes are dumb and they make fun of us. So, we decided to set the record straight. Ten of us got together, bought that puzzle and put it together. The side of the box said 2-4 years, but we put it together in 51 days!" A Blonde And A Brunette Are Running A Ranch A blonde and a brunette are running a ranch together in Louisiana. They decide they need a bull to mate with their cows to increase their herd. The brunette takes their life savings of $600 dollars and goes to Texas to buy a bull. She eventually meets with an old cowboy that will sell her a bull. "It's the only one I got for $599, take it or leave it." She buys the bull and goes to the local telegram office and says, "I'd like to send a telegram to my friend in Louisiana that says: Have found the stud bull for our ranch, bring the trailer." The man behind the counter tells her, "Telegrams to anywhere in the U.S. are $.75 per word." She thinks about it for a moment and decides. "I'd like to send one word, please." "And what word would that be?" inquires the man. "Comfortable." replies the brunette. The man asks, "I'm sorry miss, but how is your friend gonna understand this telegram?" The brunette replies, "My friend is blonde and reads REAL slow, when she gets this, she will see COM-FOR-DA-BULL." A Blonde And A Lawyer Are Seated Next To Each Other On A Flight A blonde and a lawyer are seated next to each other on a flight from LA to NY. The lawyer asks if she would like to play a fun game? The blonde, tired, just wants to take a nap, politely declines and rolls over to the window to catch a few winks. The lawyer persists and explains that the game is easy and a lot of fun. He explains, "I ask you a question, and if you don't know the answer, you pay me $5.00, and vise versa. "Again, she declines and tries to get some sleep. The lawyer, now agitated, says, "Okay, if you don't know the answer you pay me $5.00, and if I don't know the answer, I will pay you $500.00." This catches the blonde's attention and, figuring there will be no end to this torment unless she plays, agrees to the game. The lawyer asks the first question. "What's the distance from the earth to the moon?" The blonde doesn't say a word, reaches into her purse, pulls out a $5.00 bill and hands it to the lawyer. Okay says the lawyer, your turn. She asks the lawyer, "What goes up a hill with three legs and comes down with four legs?" The lawyer, puzzled, takes out his laptop computer and searches all his references, no answer. He taps into the air phone with his modem and searches the net and the library of congress, no answer. Frustrated, he sends e-mails to all his friends and coworkers, to no avail. After an hour, he wakes the blonde, and hands her $500.00. The blonde says, "Thank you," and turns back to get some more sleep. The lawyer, who is more than a little miffed, wakes the blonde and asks, "Well, what's the answer?" Without a word, the blonde reaches into her purse, hands the lawyer $5.00,and goes back to sleep. And you thought blondes were dumb. A Blonde Hurries Into The Hospital Emergency Room Late One Night A blonde hurries into the hospital emergency room late one night with the tip of her index finger shot off. "How did this happen?" the emergency room doctor asked her. "Well, I was trying to commit suicide," the blonde replied. "What?" sputtered the doctor. "You tried to commit suicide by shooting off the tip of your finger?" "No, silly!" the blonde said. "First I put the gun to my chest, and I thought, 'I just paid $6000 for these, I'm not shooting myself in the chest.'" "So, then?" asked the doctor. "Then I put the gun in my mouth, and I thought, 'I just paid $3000 to get my teeth straightened, I'm not shooting myself in the mouth.'" "So, then?" "Then I put the gun to my ear, and I thought 'This is going to make a loud noise,' so I put my finger in the other ear before I pulled the trigger. A Blonde Walks Into A Bank A blonde walks into a bank in New York city and asks for the loan officer. She says she is going to Europe on business for two weeks and needs to borrow $5000. The bank officer says the bank will need some kind of security for such a loan, so the blonde hands over the keys to a new rolls royce parked across the street in front of the bank, everything checks out, and the bank agrees to accept the car as collateral for the loan. An employee drives the rolls into the bank's underground garage and parks it there. Two weeks later, the blonde returns, repays the $5000. And the interest, which comes out to $15.41. The loan officer says, "we are very happy to have had your business, and this transaction worked out very nicely,, but we are a little puzzled, while you were away, we checked you out and found out you are a multimillionaire. What puzzles us is why would you bother to borrow $5000?" The blonde replied, "where else in New York can I park my car for two weeks for 15 bucks?"

She went to the front door of the first house and asked the owner if he had any jobs for her to do. "Well, you can paint my porch. How much will you charge?" The blonde said, "How about fifty dollars?" The man agreed and told Her that the paint and ladders she might need were in the garage. The man's wife, inside the house, heard the conversation and asked her husband, "Does she realize that the porch goes all the way around the house?" The man replied, "She should. She was standing on the porch." A short time later, the blonde came to the door to collect her money. You're finished already?" he asked. "Yes," the blonde answered, "and I had paint left over, so I gave it two coats". Impressed, the man reached in his pocket for the $50. "And by the way," the blonde added, "that's not a Porch, it's a Ferrari."

The three women quickly entered and upon finding the mirror, the brunette said, "I think I'm the most beautiful of us three" and in an instant she was surrounded by a pile of money.
