Interpretation:
“The pressure of gas present in the cylinder” should be calculated.
Concept Introduction:
Here we have used the concept of ideal gases and its equation.
► Ideal gases are the gases which obeys the ideal gas equation under all conditions of temperature and pressure. The ideal gas equation can be obtained by combining the Boyle’s Law, Charles’ Law and the
► Boyle’s Law: It states that at constant temperature, the pressure is inversely proportional to the volume
► Charles’ Law: It states that at constant pressure, the volume of the gas is directly proportional to the temperature
► Avogadro’s Law: It states that equal volumes of all gases under similar conditions of temperature and pressure contains the same number of molecules
Volume of the gas Number of molecules
Moles of the gas
► Combining these three laws, we get the ideal gas equation
where, universal gas constant
is the volume
is the number of moles
is the pressure
is the temperature
► The relation between number of moles and mass of the gas is
where, is the mass of the gas,
is molar mass of the gaseous compound
► Molar mass is the number of times a molecule of the substance is heavier than the mass of an atom of . It can be calculated by adding the atomic masses of all the atoms present in the molecule.
Given:
Volume of the cylinder,
Temperature of the gas,
Mass of gas,

Hint: Pay attention to your units. A. What is the partition function for this system? B. What are the populations of each level? Now instead, consider a system with energy levels of 0 J mol C. Now what is the partition function? D. And what are the populations of the two levels? E. Finally, repeat the second calculation at 500 K. and 500 J mol 1 at 300 K. F. What do you notice about the populations as you increase the temperature? At what temperature would you expect the states to have equal populations?arrow_forward30. We will derive the forms of the molecular partition functions for atoms and molecules shortly in class, but the partition function that describes the translational and rotational motion of a homonuclear diatomic molecule is given by Itrans (V,T) = = 2πmkBT h² V grot (T) 4π²IKBT h² Where h is Planck's constant and I is molecular moment of inertia. The overall partition function is qmolec Qtrans qrot. Find the energy, enthalpy, entropy, and Helmholtz free energy for the translational and rotational modes of 1 mole of oxygen molecules and 1 mole of iodine molecules at 50 K and at 300 K and with a volume of 1 m³.
