Heating Curves Flashcards
1
Q
What is the specific heat formula?
A
q = ΔH = mCΔT
2
Q
What is the formula for enthalpy of fusion?
A
nΔHfus
3
Q
An endothermic change is a positive or negative change in enthalpy?
A
positive
4
Q
An exothermic change is a positive or negative change in enthalpy?
A
negative
5
Q
A negative change in enthalpy is a endothermic or exothermic process?
A
exothermic
6
Q
When will energy flowing into a system in the form of heat lead to a temperature change?
A
o When there is no chemistry or phase transitions, then energy flowing into a system in the form of heat will lead to a temperature change
7
Q
What is the slope of the specific heat graph?
A
• This produces a graph of T vs q, thus the slope is actually 1/mC
8
Q
A positive change in enthalpy is a endothermic or exothermic process?
A
endothermic
