In answering the questions in this problem, assume that the molecules in air (mainly N2 and O2) have five degrees of freedom at this temperature (three translational and two rotational). What is the internal energy U of one mole of air on a very hot summer day (35∘C)? What is the internal energy U of one mole of air on a typical winter day in Boston when the air temperature is −8.0∘C.   To put these results in perspective, determine how high one mole of air has to be lifted to gain a potential energy equal to the difference in the energies found in Part A and Part B. (Take the mass of one mole of air to be 28.9 g.)

Question

In answering the questions in this problem, assume that the molecules in air (mainly N2 and O2) have five degrees of freedom at this temperature (three translational and two rotational).

What is the internal energy U of one mole of air on a very hot summer day (35∘C)?
What is the internal energy U of one mole of air on a typical winter day in Boston when the air temperature is −8.0∘C.
 
To put these results in perspective, determine how high one mole of air has to be lifted to gain a potential energy equal to the difference in the energies found in Part A and Part B. (Take the mass of one mole of air to be 28.9 g.)
