So Xi Zhang’s theory: Hydrogen bonds between multiple water molecules bring them close together. However, these molecules also repel each other (because if molecules and atoms really touched for real we’d get nuclear fusion and that’s bad). Due to this repulsion, the bondswithin the water...
Ok, at higher temperatures, atoms move more quickly, you know this from the bubbles when your kettle boils, and from the way you don’t feel like a morning run in the depth of winter on a frigid morning. Once you’ve warmed up, however, you’re more willing to jog (…ok, well, ...
But this process does not always happen easily as the plates are stiff, rough, and under a lot of pressure from surrounding plates. The tectonic plates tend to pull at or push on each other on either side of a fault for long periods of time without moving much at all, wh...

Describe how the structure of atoms would differ if the Pauli exclusion principle were not valid. What consequences would follow, both at the atomic level and at the world at large? Why are gases easier to compress than liquids and solids? Why does helium gas absorb heat? Why don't the ...
How to make a balloon car project? Why does a gymnast appear to be floating on air when she raises her arms above her head in a leap? Explain why hydrogen and helium atoms have the necessary speed to escape but why other elements, such as oxygen and nitrogen, do not. Fill in the bl...
Elon Musk, the CEO of SpaceX and Tesla, is known for his ambitious and innovative vision, as well as his determination to make it a reality. His leadership has inspired the companies’ employees and has set the bar for what is possible in the hardware engineering industry. ...
their arms in—and as such, the inner part of the accretion disk should spin faster. Astronomical observations do indeed show that the inner part of an accretion disk does spin faster. Curiously, however, it does not spin as fast as predicted by the law of conservation of angular mome...
When a wave crosses a surface at an angle from one medium into another, why does it change directions as it moves? Why are gases easier to compress than liquids and solids? How do atoms move through solids? All atoms have moving electric charges. Then, why aren't all materials ma...
downright excited, even – ahead of your move, expect stress or anxiety to bubble up at some point. The better prepared you are for it, the better equipped you’ll be to handle it. “It takes people by surprise – they underestimate the toll (moving) does take on ...
