Question:What is the density ofoxygengas at 5 atm and 27 °C? First, let's write down what we know: Gas is oxygen gas or O2. Pressure is 5 atm Temperature is 27 °C Let's start with the Ideal Gas Law formula. PV = nRT where P = pressure V = volume n = number of moles of...
2. We can apply the ideal gas equation PV = nRT. The gas constant R and the variables T and V are known in this case (T is measured, V = 1 m3), but we need to calculate P before we can solve for n. 3. To obtain a value for P, we can use the following variant[REF, eq...
It is sometimes said that the heating of atmospheric entry is caused by compressing air, as in the ideal gas law, PV = nRT. This is kind of true, but not very helpful. It's not at all obvious what to use for the volume, and whatever you use, air is rushing in and out. Having...
Going back to PV=nRT. The pressure (P) is now 2 atm (30 psi). The volumes (V) are constant. The temperature (T), like before, is also higher. But it's gone past the 212°F we'd expect at sea level because we've increased the pressure. Remember, both sides of the equation ...
Would the student have to use a different indicator to figure out the concentration of a solution of an acid with pKaof 4.83? Based on our Kacalculations in part b, we can use one of the equations on the formula sheet to figure out pKafor the original propionic acid and compare the two...
Use kinetic molecular theory to explain why approximating ideal gas behavior (i.e., PV=nRT) is reasonably accurate only at low pressures and high temperatures. Using postulates of the kinetic molecular theory, give a molecular interpretation of Boyle's law, Charles's law, and Dalton's law ...
However, instead of using different still images as a scale photograph, we use the same photograph with a floating PVC pipe as a reference scale to measure the manta ray body size. This approach provides more robust measurements, particularly when using low-cost drones with high uncertainty in ...
