2. ● Fahrenheit - Celsius
○ C = 5/9 x (F - 32)
● Celsius - Fahrenheit
○ F = 9/5 x (C + 32)
● Celsius - Kelvin
○ K = C + 273
● Fahrenheit - Kelvin
○ F to C and C to K
Temperature
3. Absolute Zero
It is a theoretical concept
● According to the 3rd law of
thermodynamics no system can reach
absolute zero
● It is the point where there is no more
kinetic energy and and the freezing point
of all matter
● -273 degrees Celsius or 0 Kelvin
4. Quantity of Heat
Heat is measured in joules and represented.
Measure of calories, which is the amount of
heat needed.
5. 4 States of matter
1.Solid
2.Liquid
3.Gas
4.Plasma
6. Melting Point and Boiling Point
● Melting point is when the temperature at
which the solid melts to become liquid
● Boiling point is when the temperature at
which liquid becomes gas.
7. 4 Laws of Thermodynamics
1) When heat moves into or out of a system,
the gain or loss of thermal energy
2) Change in heat and thermal energy
3) No system can reach absolute zero
4) Establish temperature
8. Entropy and Enthalpy
● In a few words
Entropy is how
heat moves
through a system.
● Enthalpy is
thermal potential
energy
9. Specific Heat
● The concept is the
intensive property that
describes how much
heat must be added to a
particular substance to
raise its temperature.
● Q = cmΔt
10. Heat Transfer
● Conduction -A method of heat transfer through solids
with the vibration of atoms.
● Convection - A method of heat transfer through liquids
and gases with the circulation of atoms.
● Radiation - A method of heat transfer from a light
source.
