Engineering + gas Flashcards
What is the gas law equation
PV = nRT n = no. of moles / PV = NkT N = no. of molecules
How do you find the Boltzmann’s constant?
k = R/Ra
What is Boyle’s law?
The pressure of a fixed mass of gas is inversely proportional to its volume provided (Constant temperature) p = k/v
What is Charles’s law?
The volume of fixed mass of an ideal gas is directly proportional to its absolute temperature V = kT
What is Amonton’s (Pressure) law
The pressure of a fixed mass and volume of gas is directly proportional to the absolute temperature of gas p = kT
What are the assumptions of ideal gas?
The inter-molecular force are assumed to be negligible and all collisions between the molecules and the wall of the container are assumed perfectly elastic. This suggests the internal energy of an ideal gas is entirely kinetic.
What is the kinetic theory?
It states that all matter consists of particle in constant rapid motion and that all collisions are perfectly elastic.
What is thermal equilibrium?
Its when the radiating energy is at the same rate as its absorbing energy
Define the moment of Inertia?
It’s the sum of the product of mass of each particle and the distance to the rotational axis squared
What is the formula of angular kinetic energy
1/2 * I * W^2
