Answer 8

Internal energy

Question 9

Valuedepends only on the state of the system not on how the system arrived at that state

Answer 9

State function

Question 10

Any process that absorbs heat

Answer 10

Endothermic

Question 11

Any process that releases heat

Answer 11

Exothermic

Question 12

What is enthalpy

Answer 12

Another word for heat it is abbreviated with a capital H and is an extensive property

Question 13

How does endothermic feel and get and why

How is the change in heat

Answer 13

Feels cold
Gets cold
Absorbs heat so the bonds can break
Positive

Question 14

How does exothermic feel and what is the change in heat

Answer 14

Feels warm

Change is negative

Question 15

The energy involved when forming one mole of a substance from its elements

Answer 15

Standard heat of formation

Question 16

What type of function is enthalpy

Answer 16

State function- independent of the pathway

Question 17

A measure of the systems ability to absorb thermal energy without undergoing a large change in temperature

Answer 17

Heat capacity

Question 18

Relationship between heat capacity and temperature

Answer 18

The larger the heat capacity the smaller the change in temperature

Question 19

What kind of property is heat capacity

Answer 19

Extensive- depends on amount of matter being heated

Question 20

Measure of the intrinsic capacity of a substance to absorb heat

Answer 20

Specific heat capacity

Question 21

Specific heat capacity and molar heat capacity are what type of properties

Answer 21

Intrinsic- depend on the kind of substance being heated

Question 22

What type of property is the enthalpy of reaction

Answer 22

Extensive - depends on amount of material undergoing the reaction
