Chem 103 Module 6calorie (cal) - ANSunit 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
endothermic process - ANSchemical reaction or physical change that absorbs heat
energy - ANSthe capacity to supply heat or do work
exothermic process - ANSchemical reaction or physical change that releases heat
joule (J) - ANSSI unit of energy; 1 joule is the kinetic energy of an object with a mass of 2kg
moving with a velocity of 1 m/s, 1 J = 1 kg m2/s and 4.184 J = 1 cal
kinetic energy - ANSenergy of a moving body, in joules, equal to 1/2mv^2
potential energy - ANSenergy of a particle or system of particles derived from relative position,
composition, or condition
thermal energy - ANSkinetic energy associated with the random movement of atoms or
molecules
thermochemistry - ANSstudy of measuring the amount of heat absorbed or released during a
chemical reaction or a physical change
which of the following substances would you expect to have a relatively high chemical potential
energy: Wood, Gasoline, Chalk, Water, Hydrogen Gas? - ANSWood, gasoline, hydrogen gas
heat (q) - ANStransfer of thermal energy between two substances
surroundings - ANSall matter other than the system being studied
system - ANSportion of matter undergoing a chemical or physical change being studied
temperature - ANSintensive property of matter that is a quantitative measure of "hotness" and
"coldness"
When 50.0 mL of 0.10 M HCl(aq) and 50.0 mL of 0.10 M NaOH(aq), both at 22.0 °C, are added
to a coffee cup calorimeter, the temperature of the mixture reaches a maximum of 28.9 °C
degrees. Would the amount of heat measured for this reaction be greater, lesser, or remain the
same if we used a calorimeter that was a poorer insulator than a coffee cup calorimeter?
