How much does the pressure of a gas in a rigid vessel decrease when the temperature is decreased by 1 C?
Ideal gas law: "PV = nRT"
rearranged: "P = (nR/V) * T"
therefore: "P is proportional to T if n,R,V are constant"
P = pressure
V = volume
n = amount of gas substance
R = gas constant
T = absolute temperature (in kelvin)
It is possible to say that if the temperature decrease by a certain percentage, the pressure would also decrease by the same percentage, because the two quantities are proportional. However, to know the absolute decrease in pressure due to an absolute decrease in temperature (ΔP = -?, given ΔT = -1°C), you would need to know more information, such as the initial values of P and T.

Why does ice form on a vessel when gas is released?
When gas is released from a vessel, it rapidly expands and the surrounding air temperature drops. This rapid expansion causes a decrease in pressure and can lead to a drop in temperature, resulting in condensation and freezing of water vapor in the air on the surface of the vessel, forming ice.
Why does temperature affect the air pressure?
Air temperature and air pressure are inversely proportional. As temperature increases, air pressure decreases. This is best demonstrated in an enclosed vessel.
How does blood pressure decrease in a vessel as distance from the left ventricle increase?
Pushing water through a hose, the pressure at either end is equal. This is not true with blood pressure. The blood pressure in the body changes based on distance from the left ventricle due to slowdown caused by curves, friction and variation of vessel size.
How do you calculate the amount of gas required to raise the pressure of a closed vessel to a known value?
If you know the temperature, pressure and volume of the vessel, you can calculate the amount of moles through the Ideal gas law. PV = nRT That is assuming you have ideal conditions. If not, a variance of the ideal gas law can be used in order to get the moles of your gas.
If water is contained in a closed vessel having an absolute pressure of 0.15 psia such as in the evaporator area of the absorption generator the water will boil at what temperature?
The temperature is 7 oC.
Why the pressure does not change when the volume decrease for boyle law?
There is either a leak in the vessel, or the temperature is changing. Or both.

What will be the result of the volume of the reaction vessel is decreased for the reaction H2 I2 yields 2HI?
If the volume of the reaction vessel is decreased, the reaction will shift towards the side with fewer gas molecules to relieve the pressure. In this case, since there are 3 moles of gas on the left side (H2 and I2) and only 2 moles of gas on the right side (2HI), the reaction will shift to the right to decrease the pressure, producing more HI.
Why does temperature affect the air pressure?
Air temperature and air pressure are inversely proportional. As temperature increases, air pressure decreases. This is best demonstrated in an enclosed vessel.
When there is increased resistance then arteriolar constriction and pressure drops?
Resistance changes dramatically with changes in diameter of blood vessels (arterioles are one type of blood vessel). If you INCREASE the diameter of the arteriole, you DECREASE the resistance and thus DECREASE the blood pressure.

What is the surface area of a pressure vessel?
The answer depends on the pressure vessel.
How does blood pressure decrease in a vessel as distance from the left ventricle increase?

What will be changes in pressure if the number of molecules are halved in a vessel?
The pressure will also halve in this case.The pressure will also halve in this case.The pressure will also halve in this case.The pressure will also halve in this case.
What are deaerators?
Deaerator is Device or vessel where dissolved gases removed from the water by using steam (pressure corresponding to saturation temperature)
What happens when blood vessels dialate?
When blood vessels dilate, there is a decrease in resistance to blood flow and blood is shunted to that part of the circulation. In addition, there is a decrease in pressure in the vasculature so that if the dilation is widespread, blood pressure falls. Blood vessels dilate because of decreased contraction of the smooth muscle cells that make up the medial layer of the vessel wall. This can be caused by release of dilating substances from the inner (endothelial) layer or from a decrease in the level of constricting substances such as norepinephrine from nerves or angiotensin in the blood. Many antihypertensive drugs work by causing dilation.
