VERSIONS QUESTIONS AND CORRECT
VERIFIED ANSWERS WITH RATIONALES (100%
CORRECT) A+ GRADED ASSURED
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
