Chapter 20, Problem 37AP

The latent heat of vaporization for water at room temperature is 2 430 J/g. Consider one particular molecule at the surface of a glass of liquid water, moving upward with sufficiently high speed that it will be the next molecule to join the vapor. (a) Find its translational kinetic energy. (b) Find its speed. Now consider a thin gas made only of molecules like that one. (c) What is its temperature? (d) Why are you not burned by water evaporating from a vessel at room temperature?

A space probe is far away from the Sun, or any other sources of energy. It is kept warm (so the electronics work) by waste heat from a radioactive source. The radioactive source emits energy at a rate of 625W. The space probe can be modelled as a uniform sphere of metal. The radius is 1.3m, and the metal has a high thermal conductivity, so the probe is at a uniform temperature. The coefficient of linear expansion for this metal is 2.3 × 10-5 K-¹. 8. Suppose that the probe emits as a blackbody (with e = 1). What is the equilibrium temperature of the space probe? (a) 30K (b) 90K (c) ***150K (d) 240K (e) 320K 9. Suppose that the space probe is currently at temperature 200K, and it was launched from Earth at a temperature of 300K. By how much has the probe's volume decreased relative to the size at launch? (a) 2.1 x 10-2m³ (b) 4.2 × 10-²m³ (c) ***6.3 × 10-²m³ (d) 8.5 × 10-2m³ (e) There is not enough information to determine this.
Your answer is partially correct. The temperature near the surface of the earth is 297 K. A xenon atom (atomic mass = 131.29 u) has a kinetic energy equal to the average translational kinetic energy and is moving straight up. If the atom does not collide with any other atoms or molecules, then how high up would it go before coming to rest? Assume that the acceleration due to gravity is constant during the ascent.

A thermocouple, with a spherical junction diameter of 0.5 mm, is used for measuring the temperature of hot air flow in a circular duct. The convection heat transfer coefficient of the air flow can be related with the diameter (D) of the spherical junction and the average air flow velocity (V) as h = 2.2(V/D)0.5, where D, h, and V are in m, W/m2?K and m/s, respectively. The properties of the thermocouple junction are k = 35 W/m?K, r = 8500 kg/m3, and cp = 320 J/kg?K. Determine the minimum air flow velocity that the thermocouple can be used, if the maximum response time of the thermocouple to register 99 percent of the initial temperature difference is 5 s.
