Chapter 6

Question 1

Heat

Answer 1

Energy transferred between 2 object bc of their different temps

Question 2

Work

Answer 2

Energy required to move an object a given distance

Question 3

Law of energy conservation

Answer 3

Energy can’t be created or destroyed

Only converted from one form to another

Ex. PE TO KE or chemical energy to heat

Question 4

Negative E el

Answer 4

More stability

Question 5

System

Answer 5

Part that’s the focus of thermochemical study

Question 6

Isolated
Close
Open systems

Answer 6

Isolated-no NRG or matter exchange with surroundings

Closed- exchange NRG not matter

Open- exchange both

Question 7

Exothermic vs endothermic in terms of q

Answer 7

Exo- q<0

Endo- q>0

Question 8

Internal energy

Answer 8

All energy KE + PE in the system

Delta E = E final- E initial

Question 9

Types of molecular motion

Answer 9

Translational
Rotational
Vibrational

Question 10

Law of conservation of energy in terms of systems and surrounding

Answer 10

Delta E of system = - Delta E of surroundings

Bc if system gains energy the surroundings lose energy and VV
