Thermochemistry Flashcards
S2 (Q4)
Definition of energy
To do work or transfer heat
Definition of Potential energy
stored energy that an object
Definition of Kinetic energy
energy of motion
How is Potential energy converted
Highest point: Potential energy = max while Kinetic energy = 0
Lowest point: Potential energy = 0 while Kinetic energy = max
State the Law of Conservation of Energy
energy cannot be created nor destroyed but can be converted
Define heat and explain flow
energy transferred between samples of matter (higher temp to lower temp)
Define temp
measure the average kinetic energy of the particles
What is thermochemistry
study of the transfers of energy and heat that accompany physical/chemical change
Explain System
specific matter being observed
Explain Surroundings
everything else besides the system
Define Specific heat
amount of energy required to raise the temp
Equation for heat flow
q = c * m * ^T
Define Calorimetry
measurement of heat flow
