How is the helium in the tank different from the helium in the balloon?
Helium balloons are usually mylar, a metal-coated plastic film while blow-up balloons are usually latex. Helium balloons are usually filled with helium of a decent purity, while blow-up balloons basically have the same gas mixture as the atmosphere around us. A little less oxygen and a little higher humidity if inflated by humans, exactly the same if inflated by a pump. Helium balloons will fly or float in the air, while blow-up balloons won't.
What is the difference between free electron theory and nearly free electron theory?
free electron model not take into account the potential neither the electron interaction. nearly free electron take into account the potential.J.C. Aguiar
What are the key differences between the nearly free electron model and the tight binding model in the context of electronic band structure calculations?
The key differences between the nearly free electron model and the tight binding model in electronic band structure calculations are in how they treat electron interactions. In the nearly free electron model, electrons are considered to move almost freely through the crystal lattice, with only weak interactions with the lattice. This model assumes that electrons behave like free particles in a potential well created by the lattice. On the other hand, the tight binding model considers strong interactions between electrons and the lattice. In this model, electrons are tightly bound to specific atomic sites within the lattice, and their movement is influenced by the potential energy from neighboring atoms. Overall, the nearly free electron model is more suitable for describing metals and simple semiconductors, while the tight binding model is better for complex materials with strong electron-lattice interactions.
In which Direction is nearly all galexies moving in?
Nearly all galaxies in the universe are moving away from each other due to the expansion of the universe. This is known as the expansion of the universe or Hubble expansion.
A material through which nearly all light passes is?
A material through which nearly all light passes is called a transparent material.
What would happen if you put two positively charged balloons together?
You then have two balloons in very nearly the same place.
What happens to the graph when x is nearly zero?
When x is nearly zero,y increases in value.
What is good about hot air balloons?
Hot air balloons are beautiful. They fly silently (or nearly so) and drift with the wind. It is a very relaxing and unique way to fly. You pass just over the trees and can still hear the twitter of the birds, cows mooing, and the like.
What happens if the digestive system stopped working?
Nearly always, death.

Of what economic importance is the painting and paper hanging industry?
The painting and paper hanging industry is worth an estimated $13 billion in income, as per the latest statistics released by the U.S. Census Bureau. Nearly all of this amount was for construction work.
What happens to the island as a result of the fire the boys start?
nearly starts a forest fire
What happens to the temperature from the surface of the sun to its center?
stuff happens Hydrogen atoms need nearly 30 kT to be torn apart This happens on the surface of the sun We can tell this from the line spectra
