Chapter 3 Vocabulary

One day, a guy named Chuck decides he wants to go to the moon.

Solids

Okay, so Chuck has never even had a solid job for more than 3 months, but that doesn’t seem to bother him. He’s determined.

Liquids

He wants to go to the moon TODAY, so he decides to load up on liquids from Starbucks and Walmart.

Absolute Zero

0 Kelvins

When Chuck told his friends about his idea, they were like “Dude. You don’t even have a spaceship. You have absolute zero chances of getting to the moon, man.”

Gas

Chuck said, “sure I do, I just need to load it up on gas”

Kinetic Energy

Lucky for Chuck, one of his friends happened to be a scientist named Jude. “Hey Jude,” Chuck said, “someone said I needed to know something about kinetic energy to get to the moon. Can you help?”

Pressure

“Sure can. This is a lot of pressure though. Are you sure you want to do it?”

Charles’s LawV1 = V2

T1 = T2

“yeah. I saw this guy once. He got pretty far with a lawn chair attached to a bunch of balloons. Any suggestions?” “well, you’ll probably need to use Charles’s Law to figure how much gas to put into the balloons,” Jude said.

Boyle’s Law

P1 V1 = P2 V2

“What in the world is charles’s Law? I’ve heard of Boyle’s Law. Is it sort of like that?” chuck asked.

“YES!” Jude said. “you’ll need to know that one too.”

Phase Change

“Now, the air in my balloons won’t go through any weird phase changes will it?” chuck asked.

“No, you should be fine,” Jude answered.

Endothermic

heat

“On the news, I heard that all this endothermic heat is melting the iceburgs. Do I need to be worried about that?...

Exothermic

…and what about exothermic heat? If all my heat goes away, won’t I be cold?” Chuck asked again.

“Do you ever run out of questions??” Jude remarked. “No, you should be fine. It might get a little chilly up there, so take a jacket, though.”

Heat of Fusion

344 Joules of Energy

1g of ice

fusion=Melting

“Okay, I’m almost done, I promise. But what about the heat of fusion? Won’t it melt my super awesome aircraft?”

“Don’t worry about that unless you’re going to the sun, Chuck,” Jude commented.

Heat of Vaporization

Gains 2261 Joules of energy 1 gram of water

“So I guess I shouldn’t be too worried about the heat of vaporization turning my coffee into gas, either, huh?” he asked.

“Right.” Jude said.

Vaporization

“Okay, so what if all of my water supply vaporizes in the air, and I die of dehydration?

Evaporation“Or would it be called evaporation? I’m confused,” Chuck said.

“Evaporation is a kind of vaporization. Don’t worry.” Jude was getting tired of his questions by now.

Vapor Pressure

Temperature increase=

Vapor pressure increase

“Just don’t take any sodas up there. The vapor pressure will make them explode!” Jude warned.

Gas to liquid

“And if you get hot, you’ll start condensing, so take an extra shirt,” Jude called after him.

“You sound like my mom!” Jude said back.

Sublimation

“Fine then. I hope your spaceship or whatever goes through sublimation and turns into air!…

Deposition

Gas! Liquid

..and all the gas in your balloons turns into water and you fall to the ground! Your idea will never work anyway.” Jude called after Chuck while he was walking away.

So Chuck, not feeling so great, but determined, went home and fell asleep, thinking about his journey the next day. When he woke up, he got right to work. He used all of his knowledge that Jude had given him, 27 balloons, a lawn chair, and lots of duct tape and finally..

See ya!

..He flew away.
