Chapter 19: TEMPERATURE, HEAT,AND THE FIRST LAW OF THERMODYNAMICS1. If two objects are in thermal equilibrium with each other:A. they cannot be movingB. they cannot be undergoing an elastic collisionC. they cannot have diferent pressuresD. they cannot be at diferent temperaturesE. they cannot be falling in Earth’s gravitationalfeldans: D2. When two gases separated by a diathermal wall are in thermal equilibrium with each other:A. only their pressures must be the sameB. only their volumes must be the sameC. they must have the same number of particlesD. they must have the same pressure and the same volumeE. only their temperatures must be the sameans: E3. A balloon isflled with cold air and placed in a warm room. It is NOT in thermal equilibriumwith the air of the room until:A. it rises to the ceilingB. it sinks to theFoorC. it stops expandingD. it starts to contractE. none of the aboveans: C4. Suppose object C is in thermal equilibrium with object A and with object B. The zeroth lawof thermodynamics states:A. that C will always be in thermal equilibrium with both A and BB. that C must transfer energy to both A and BC. that A is in thermal equilibrium with BD. that A cannot be in thermal equilibrium with BE. nothing about the relationship between A and Bans: C5. The zeroth law of thermodynamics allows us to defne:A. workB. pressureC. temperatureD. thermal equilibriumE. internal energyans: C270Chapter 18: TEMPERATURE, HEAT, AND THE FIRST LAW OF THERMODYNAMICS
6. If the zeroth law of thermodynamics were not valid, which of the following could not be con-sidered a property of an object?A. PressureB. Center of mass energyC. Internal energyD. MomentumE. Temperatureans: E7. The international standard thermometer is kept:A. near Washington, D.C.B. near Paris, FranceC. near the north poleD. near Rome, ItalyE. nowhere (there is none)ans: E8. In constructing a thermometer it is NECESSARY to use a substance that:A. expands with rising temperatureB. expands linearly with rising temperatureC. will not freezeD. will not boilE. undergoes some change when heated or cooledans: E9. The “triple point” of a substance is that point for which the temperature and pressure are suchthat:A. only solid and liquid are in equilibriumB. only liquid and vapor are in equilibriumC. only solid and vapor are in equilibriumD. solid, liquid, and vapor are all in equilibriumE. the temperature, pressure and density are all numerically equalans: D10. Constant-volume gas thermometers using diferent gases all indicate nearly the same temper-ature when in contact with the same object if:A. the volumes are all extremely largeB. the volumes are all the sameD. the pressures are all extremely largeC. the pressures are the sameE. the particle concentrations are all extremely smallans: EChapter 18: TEMPERATURE, HEAT, AND THE FIRST LAW OF THERMODYNAMICS271
11. A constant-volume gas thermometer is used to measure the temperature of an object. Whenthe thermometer is in contact with water at its triple point (273.
