Unit 6

Question 1

What is endothermic characteristics

Answer 1

Heat is absorbed
Positive energy
Energy is a reactant
Breaking bonds
Temp goes down

Question 2

What is exothermic characteristics

Answer 2

Heat is exited
Negative heat change
Energy is a product
Bonds are formed
Temp goes up

Question 3

What happens when two different molecules have different temperature

Answer 3

Heat transfer occurs transferring energy from warm to cold making them the same temperature

Question 4

what is specific heat capacity

Answer 4

The amount of J it takes for 1 g of a substance to be raised by 1 degree.

Question 5

what is thermal conductivity

Answer 5

how much a substance has the ability to transfer heat

Question 6

what is the heat absorbed, or q equation from surroundings to reaction

Answer 6

the q of the surroundings is the negative q of the reaction

Question 7

What is the equation to find enthalpy in a reaction

Answer 7

change in H is equal to the q of the reaction divided by number of molst

Question 8

what is the difference between q and change in H

Answer 8

q is specific to a reaction and depends on the amount

h is a ration so it will always stay the same in a given reaction

Question 9

if two different termperatured waters were mixed how do I find the closest new heat

Answer 9

mcat1 = mcat2

(conservation of energy equation)
