Unit 5 - Coggle Diagram
Unit 5
Enthalpy
P x deltaT x C
W = -P x deltaV
H = E + P x V
deltaH = deltaE + P x deltaV
Q = -Q
W = Force x Distance
W = -P x delta V
Energy
Kinetic energy
Energy that is motion
electric, light, motion
Potential Energy
energy that is positional or chemical
electrostatic, gravitational, magnetic
Systems
Open system
can lose energy
Closed system
no loss of energy
Internal energy
sum of all kinetic & potential energy
1 KJ = 1000 J
Law of Thermodynamics
Energy can't be created or destroyed
Calorimetry
the measurement of heat flow
State condition
when the atmospheric pressure is at 1 atm
Hess's law
you can skip the small steps to get to the big picture
A + B = C
C + D = E
A + B + D = E
