They altered the deal on Vader's helmet (jpeg & gif comparison) (self.StarWars) submitted 4 months ago by pldkn. In a previous Japanese trailer, we could see Darth's menacing pose as he turns to the camera - but mostly I saw his awkward neck situation. In a new Chinese trailer, they show the same shot again, but this time it's obviously edited. No more weird neck situation, much more sinister looking indeed.
Air parcels, in a horizontal air pressure gradient, flows in a direction to eliminate the pressure gradient. The force that causes air parcels to move as the consequence of an air pressure gradient is known as the pressure gradient force and always acts directly perpendicular to isobars and toward lowest pressure.
This shows the pressure of the gas is directly proportional to the absolute temperature of the gas. Doubling the temperature will double the pressure for a fixed mass of gas at constant volume. The gradient of the slope is the constant in Charlesâ Law. It also shows that if the gas is cooled to absolute zero then the energy of the molecules is at the lowest energy state and therefore cannot generate any pressure.
