Which of the following variables is not necessary to quantitatively describe a gas?
Which of the following variables is not necessary to quantitatively describe a gas?
A. The number of moles of gas present
B. The size of the vessel containing the gas
C. The shape of the vessel containing the gas
D. The temperature of the gas
Homework Answers
The shape of the vessel because the shape doesn't effect the quantity if the gas and infact the gas has the behavior to take the shape of the container in which it is poured.
Also in ideal gas law given by pV=nRT doesn't talks about the shape of the container containing gas

Answer the following questions related to diffusion. Quantitatively describe the boundary conditions for the well-known assumption of a semi-infinite solid. Why is Qd for diffusion of Fe into gamma-iron greater than Qd for diffusion of C into gamma -iron? If the temperature was increased to 1100 degree C, how would you expect the carburizing time to change? What accounts for this change at the atomic level and how does it affect D, Do, and Qd?

Which of the following is the correct relationship between pressure and moles of gas, according to the kinetic molecular theory, at constant temperature and volume? Select the correct answer below: A) They don't depend on each other. B) They can be both directly and inversely proportional to each other depending on the circumstances.
