I will take the best 8 out of 10 assignment marks.
Assignment 1: Assigned Jan 15, Due Jan 22 (for this assignment, you will need to refer to this link for information on the Martian atmosphere)
If you don't have the textbook yet, click here for Probs. 1.16 and 1.17.
1. (a) Compute the mass of a mole of Martian air. Assume that nitrogen and oxygen are in their usual diatomic forms. Compare the result to the mass of a mole of dry Earth air. Which is more massive?
(b) What is the volume of a mole of Martian air at the surface of Mars and at a typical Martian temperature of 250 K? What is the linear dimension corresponding to this volume (assume a simple cube geometry)?
(c) Compute the volume of a mole of Earth's air at Earth's surface at room temperature and compare it to the result from part (b).
(d) Suppose you took a mole of Martian air and transported it to the Earth's surface (not allowing it to mix with Earth's air) where it came to room temperature. Now compare its volume to the volume of a mole of Earth's air.
2. Do problem 1.16 in the text, parts a, b, and c only. Note that this problem assumes that the temperature in the Earth's atmosphere is constant; this is clearly not true but the variation in temperature is much less than the variation in pressure so your results should be approximately correct.
3. Identify each of the following quantities as extensive or intensive and provide the SI units for each:
pressure (P), temperature (T), molar specific volume (i.e. volume per mole) (v), internal energy (U), heat capacity (either CP or CV), specific heat (either cP or cV), stress on a rod (σ), electric charge (Q)
4. Do problem 1.17 in the text, parts a and b only. For part (a), you will need to solve a quadratic equation for V/n. There will be two roots. Calculate the volume per molecule and the linear separation between molecules and provide a brief physical argument as to why one root can be chosen over the other. At low T, is the pressure higher or lower than the ideal gas pressure? At high T, is the pressure higher or lower than the ideal gas pressure?
