Assignment:
Question 1:
(a)2.0g of Nitrogen gas is at 270C in a fixed volume. If 20% of its total internal energy is due to rotation what is the average velocity of nitrogen molecules?
(b)What will be the temperature 2.0 g of Helium gas in a fixed volume if the average velocity of its molecules is 20 m/s ?
(c)Plot schematic of Cv v/s T curve based for nitrogen and helium gas based on Kinetic theory.
Question 2:
(a)200g of melting ice is introduced to a huge lake at 270C. Find the total entropy change of ice-lake system.
(b)200g of melting ice is introduced to a huge lake at 0.20C. Find the total entropy change of ice-lake system.
(c)Can you draw any conclusion based on result? (Hint: tends to reversible, irreversible etc)
