Yichen now talking about the 2nd law of thermodynamic and thermal efficiency! 1/26 Everyone would like perpetual motion to be possible, but folks who've studied thermodynamics know it isn't. If you haven't had a chance to study thermo, this series of tweets will give you the knowledge without the pain 2/26

First up Maggie and Sarah tweeting about the first law of thermodynamics and how fans actually work! 1/30 We all know there is nothing like the relief of a cool breeze from a fan on a hot day. But, have you ever thought how a fan makes things feel colder? 2/30

Charlie and Laney now taking over with our explainer on the concept of boiling point elevation and freezing point depression! 1/ How much salt do YOU add to YOUR pasta water?

We use refrigerators everyday to keep our foods fresh and drinks cool. However, did you ever stop and think about how refrigerators work? (⁎⁍̴̛ᴗ⁍̴̛⁎) The principle of refrigeration is not magic! Imagine your chore for today is to get water from a nearby river. The best thing to do is to use buckets. Moving something you can see is easy.

It seems like every time we buy a new car the fuel efficiency does not significantly increase. It has been 30 years! Why can't scientists make a breakthrough?! #HeatEngines #Explained #ChemE (1/31) Today’s passenger cars have an average gas mileage of about 31 MPG while cars built 30 years ago still get 27 MPG.

Yup this is only a 15% increase in 30 years. But why? (2/31)

Hi! This is Cammie and Reagan, & over the next few hours, we're going to tell you all about the elusive concept of fugacity!

Before you scroll past & lose some pretty valuable information, ask yourself this: do you like beer? If you answered no, don’t fret: this thread is for you! We’re taking a deep dive into two different camps of beer, comparing their taste & texture through the lens of fugacity. You don’t have to settle for draft beer any longer, & this is why!

Judah and Will now taking over with our explainer on the concept of Lower Flammability Limit and Safety Student: I just saw a movie where a the villain shot a gas canister, and it caused a big explosion? How is it possible for a liquid to cause an explosion? 1/34

Have you ever been scared that leaving the refrigerator door open would freeze your kitchen like Spongebob’s did? Have you thought about just standing in front of the fridge with the door open on a hot day? Interesting thoughts, but totally wrong! No machine can be 100% efficient, which would mean it takes the same amount of energy out of the inside than it puts out. Because of this, a refrigerator actually puts out more heat into the room than it removes from inside!
