Answer:
a)
b)
c)
d)
e)
Explanation:
a) Let's recall the definition of work.
Because the system is a quasi-static isobaric expansion, P is constant here, therefore:
b) Using the ideal gas equation we have:
(1)
and (2)
We can note that n times R is a constant in (1) and (2), so we can equal those equations.
(3)
Let's solve T₂ for (3), let's recall that P₁ = P₂, so they canceled out
c) Using the equation of ideal gas we have:
d) We can write the internal energy as a function of Cv, and as we know the Cv is 1.5R for a monoatomic gas.
e) Using the first law of thermodynamic, we have:
Finally,
Have a nice day!
