CHAPTER 18 Temperature and the Kinetic Theory of Gases 1* True or false: (a) Two objects in thermal equilibrium with each other must be in thermal equilibrium with a third object. (b) The Fahrenheit and Celsius temperature scales differ only in the choice of the zero temperature. (c) The kelvin is the same size as the Celsius degree. (d) All thermometers give the same result when measuring the temperature of a...
