Thermochemistry - Coggle Diagram
Thermochemistry
Is the
Study of heat absorbed/released during a chemical reaction
Which involves
The
system
Which is
The chemical substance(s) under study
Which can undergo
A
physical
chage
A
chemical
change
Which can be
Closed
Meaning
Only
energy
Isolated
Meaning
Nothing
Open
Meaning
Energy
and
matter
Can pass the
system-surroundings boundary
The
surroundings
Which is
Everything else in the universe not part of the system
Where
If energy is
released
to it
The reaction is
Exothermic
If energy is
absorbed from
it
The reaction is
Endothermic
Using
Thermal energy
Involving
Eₖ
Which is
The energy of
motion
of the atoms themselves
And is
1 more item...
Which can be
4 more items...
Eₚ
+
Which is
The energy stored in the bonds of a substance, which are released when those bonds break
Taking the form of
3 more items...
Which is also known as
Internal energy
Where
Chemical energy
Can be used in
2 more items...
Which can be calculated using
Calorimetry
Which is
The process of
measuring
energy changes during a physical or chemical change
Which can shown using
A
heating curve
Where
2 more items...
Using the formula
q = mc∆T
Where
m = mass (g)
c = specific heat capacity
Which is
1 more item...
Of
water
is
1 more item...
q = transfer of energy (J)
Where if
2 more items...
∆T = the
final
temperature subtract the
initial
temperature
Where
Heat
is thermal energy in motion from one substance to another
Temperature
is the average Eₖ of a substance
And
Heat
always flows from a system with a
higher temperature
to one with a
lower temperature
