CHEM 103 MODULE 3 NOTES. 3.1: THERMOCHEMISTRY Thermodynamics is the study of the relationship between heat and other forms of energy, particularly mechanical work. Thermochemistry is the part of thermodynamics that deals with the quantity of heat given off or absorbed during a chemical reaction. The quantity of heat given off or absorbed during a physical change or temperature change can also be studied, and we will refer to this process as calorimetry. In order to adequately discuss thermoch...

CHM 471 BIOPHYSICAL CHEMISTRY I EXAM 1 REVIEW Gibbs Free Energy - ANS-ΔG = ΔH-TΔS ΔG = -TΔS_total ΔG is a measure of the maximal, non-expansion work a system can perform. Entropy change (ΔS) - ANS-ΔS = q_rev/T Entropy change for physical or chemical transformation approaches 0 as T -> 0. Entropy of all perfectly crystalline substances are the same at T = 0 K, and are equal to 0. Carnot Cycle efficiency - ANS-Ɛ = -w_cycle/q = (Th-Tc)/Th Maximum eff...

IB-Physics-Core-Notes Topic 2 Mechanics 2.1 Kinematics 2.1.1 Define displacement, velocity, speed and acceleration. Displacement- Defined as the change in position of an object. Displacement is a quantity that has both direction and magnitude, it is a vector. Measured in metres. Speed- How far an object travels in a given time. Rate of change of distance (ms-1) Velocity- The vector version of speed. Tells us the magnitude of how fast an object is moving and the direction in wh...
