Chapt. 19 Thermodynamics I: Temperature, Heat, First Law Multiple-Choice Problems 019 qmult 00100 1 4 4 easy deducto-memory: zeroth law and temperature 1. The zeroth law of thermodynamics allows us to deFne the function of state (or thermodynamic state variable): a) pressure. b) respiration. c) expiration. d) temperature. e) entropy. 019 qmult 00110 1 1 1 easy memory: temperature a ratio Extra keywords: physci I’ve Fnally concluded intensive quantities are ratios 2. Absolute or Kelvin temperature in modern physical understanding is, in fact, a ratio of quantities: these quantities can be determined by addition. There are a variety of ratios that can be used to determine temperature. The simplest ratio to understand is set by the ideal gas law. Because temperature is a ratio, a sample of any size above the microscopic level can have a) any temperature at all, except absolute zero (or so it seems) and inFnite temperature. b) only negative temperatures. c) only temperatures proportional to its volume.
