Chem 103 Module 6 Latest Updated - Actual Exam Questions and 100% Verified Correct Answers Guaranteed A+
bomb calorimeter - CORRECT ANSWER: device designed to measure the energy
change for processes occurring under conditions of constant volume; commonly used for reactions involving solid and gaseous reactants or products
calorie (cal) - CORRECT ANSWER: unit of heat or other energy; the amount of energy required to raise 1 gram of water by 1 degree Celsius; 1 cal is defined as 4.184 J
calorimeter - CORRECT ANSWER: a device used to measure the amount of heat
absorbed or released during chemical or physical processes
calorimetry - CORRECT ANSWER: process of measuring the amount of heat involved
in a chemical or physical process
chemical thermodynamics - CORRECT ANSWER: area of science that deals with the
relationships between heat, work, and all forms of energy associated with chemical and physical processes
endothermic process - CORRECT ANSWER: chemical reaction or physical change that
absorbs heat
energy - CORRECT ANSWER: the capacity to supply heat or do work
enthalpy (H) - CORRECT ANSWER: is an energy like internal energy (E). The most
important attribute of H is ΔH = Qp, the heat transferred at constant pressure
exothermic process - CORRECT ANSWER: chemical reaction or physical change that
releases heat
expansion work (pressure-volume work) - CORRECT ANSWER: work done as a
system expands or contracts against external pressure
first law of thermodynamics - CORRECT ANSWER: internal energy of a system
changes due to heat flow in or out of the system or work done on or by the system
heat (q) - CORRECT ANSWER: transfer of thermal energy between two substances
heat capacity (C) - CORRECT ANSWER: extensive property of a body of matter that
represents the quantity of heat required to increase its temperature by 1 degree Celsius (or 1 kelvin)
