Ch 7 Lec 2 - Thermochemistry

Question 0

total energy of a system, including translational kinetic energy of molecules and energy associated with rotations, etc. in the molecules

Answer 0

internal energy

Question 1

first law of thermodynamics says that energy is neither blank nor blank

Answer 1

created, destroyed

Question 2

heat only exists during a blank of the system

Answer 2

change

Question 3

internal heat equation

Answer 3

deltaU = q + w

Question 4

change in internal energy in an isolated system is blank

Answer 4

0

Question 5

change in internal heat of a system is equal to negative the internal heat of blank

Answer 5

surroundings

Question 6

any property that has a unique value for a specified state of a system

Answer 6

functions of state

Question 7

density is a blank function because no matter how water is formed, it still has the same density

Answer 7

state

Question 8

the sum of the internal energy and the pressure-volume product of a system

Answer 8

enthalpy

Question 9

enthalpy equation

Answer 9

H = U + PV

Question 10

the enthalpy change that occurs in the formation of one mole of a substance in the standard state from the elements of the substance in their standard states

Answer 10

standard enthalpy of formation
