Pre-AP Chemistry Exam 1
energy is the capacity to - correct answer-do work or produce heat
potential energy is due to an object's - correct answer-position
kinetic energy is due to an object's - correct answer-motion
variable for heat - correct answer-q
heat involves a transfer of energy from ___ objects to ___ objects - correct answer-warmer
to cooler
standard unit of heat - correct answer-Joule, J
specific heat capacity - correct answer-the quantity needed to raise the temperature of 1
gram of a substance by 1 degree C
the ___ the specific heat, the more energy required - correct answer-higher
calorimetry - correct answer-the science of measuring heat flow
calorimetry equation - correct answer--q released = +q absorbed (-mcΔT = +mcΔT)
