Temperature. 2 a) increase as go from one mole of solid to two moles of aqueous ions (one mole of Na+(aq) and one mole of Cl-(aq)) b) decrease as go from one mole of liquid to one mole of solid. c) increase as go from two moles of gas to three moles of gas. d) decrease as go from four moles of gas to two moles of gas.

2. The zeroth law of Thermodynamics 2.1 Thermodynamical systems Before we embark on deriving the laws of thermodynamics, it is necessary to define the main vocabulary we will be using throughout these lectures. Definition 2.1.1 — ‘Thermodynamical system’ (or ‘system’). Whatever “macroscopic” part of the Universe we select for study.
into doing work. This statement of energy conservation is the first law of thermodynamics, which is defined more formally below. Related End-of-Chapter Exercises: 1 and 13. The first law of thermodynamics is a statement of energy conservation as it relates to a thermodynamic system. Heat, which is energy transferred into or out of a system, can be

First law of thermodynamics This is the law of conservation of energy for a thermo-dynamic system. Second law of thermodynamics This law speci es the direction in which heat (molec-ular kinetic energy) may ow during a thermodynamic process. 1.2 The atmosphere The earth’s atmosphere is a mixture of gases. The chief variable constituent is ...

Chapter 3 The First Law 3.1 Assume you have a metal spring that obeys Hooke’s law: F D c.l l0/, where F is the force exerted on the spring of length l, l0 is the length of the unstressed spring, and c is the spring constant. Find an expression for the work done on the spring when you reversibly compress it from length l0 to a shorter length l0.
