Chapter 3: Q9DQ (page 639)

Imagine a gas made up entirely of negatively charged electrons. Like charges repel, the electrons exert repulsive forces on each other. Would you expect that the temperature of such a gas would rise, fall, or stay the same in a free expansion? Why?

Short Answer

Expert verified

There will be a fall in the temperature of the gas.

Step by step solution

01

Step 1:

In the expansion, the repulsive force between the electrons would do positive work as electrons move apart.

O~=0and W > 0 so U > 0 and temperature would fall.

02

Step 2:

Therefore, the temperature of the gas will fall.

(a) Equation (17.12) gives the stress required to keep the length of a rod constant as its temperature changes. Show that if the length is permitted to change by an amount 鈭哃 when its temperature changes by 鈭員, the stress is equal toFA=Y(鈭�LL0鈥�伪鈭�T)

where F is the tension on the rod, L0 is the original length of the rod, A its cross-sectional area, its coefficient of linear expansion, and Y its Young鈥檚 modulus. (b) A heavy brass bar has projections at its ends (Fig. P17.79). Two fine steel wires, fastened between the projections, are just taut (zero tension) when the whole system is at 20掳C. What is the tensile stress in the steel wires when the temperature of the system is raised to 140掳C? Make any simplifying assumptions you think are justified, but state them.

The inside of an oven is at a temperature of 200掳 C (392掳 F). You can put your hand in the oven without injury as long as you don鈥檛 touch anything. But since the air inside the oven is also at 200掳 C, why isn鈥檛 your hand burned just the same?

You propose a new temperature scale with temperatures given in 掳M. You define 0.0掳M to be the normal melting point of mercury and 100.0掳M to be the normal boiling point of mercury. (a) What is the normal boiling point of water in 掳M? (b) A temperature change of 10.0 掳M corresponds to how many 掳C?

A cylinder contains 0.0100 mol of helium at T = 27.0掳C. (a) How much heat is needed to raise the temperature to 67.0掳C while keeping the volume constant? Draw a pV-diagram for this process. (b) If instead the pressure of the helium is kept constant, how much heat is needed to raise the temperature from 27.0掳C to 67.0掳C? Draw a pV-diagram for this process. (c) What accounts for the difference between your answers to parts (a) and (b)? In which case is more heat required? What becomes of the additional heat? (d) If the gas is ideal, what is the change in its internal energy in part (a)? In part (b)? How do the two answers compare?

An asteroid with a diameter of and a mass 10Kmof impacts the earth 2.60脳1015Kgat a speed of 32.0KmKm landing in the Pacific Ocean. If 1.00% of the asteroid鈥檚 Kinetic energy goes to boiling ocean water (assuming an initial water temperature of 10.0掳C),what mass of water will be boiled away by the collision?(For comparison , the mass of water contained in Lake Superior is about 2脳1015Kg. )
