Calculus (pleas help!!!)
Find the absolute maximum and absolute minimum values of the function f(x)=(x−2)(x−5)^3+11 on each of the indicated intervals. Enter -1000 for any absolute extrema that does not exist. (A) Interval = [1,4] Absolute maximum = Absolute minimum = (B) Interval...

What happens to pressure when you increase the temperature Of a gas? PV=nRT if volume is constant, increasing the right side has to increase the left side. Pressure is directly related to absolute temperature, given volume is constant. Isn't this Charles' Law?

Chemistry
A deep-sea diver uses a gas cylinder with a volume of 13.0 L and a content of 50.1 g of O2 and 33.4 g of He. Calculate the partial pressure of each gas and the total pressure if the temperature of the gas is 22°C. I got PO= 5.82, PHe=15.5 and Ptotal=21.4 but it says that ...

Chemistry
If the reaction Fe2N(s) + 3/2H2(g) -> 2Fe(s) +NH3(g) comes to equilibrium at a total pressure of 1 bar, analysis of the gas shows that at 700. and 800.K, PNH3/PH2=2.165 and 1.083 respectively, if only H2(g) was initially present in the gas phase and Fe2N(s) was in ...

Physics Urgent
A container of volume V = 103 cm3 has a mass of 30.0042 g when evacuated. When the container is filed with an unknown gas of pressure p = 4.72 atm at temperature T = 20oC, the mass of the system increases to 30.9508 g. Assuming that the unknown gas behaves like an ideal gas, ...
