3. CHEMICAL PROPERTIES
A chemical property is any of a material's properties that becomes evident during, or after, a chemical reaction; that is, any quality that can be established only by changing a substance's chemical identity.
Examples: flammability, reactivity with other chemicals; enthalpy of formation; heat of combustion; oxidation states; chemical stability; types of chemical bonds that will form
Scientists use chemical properties to predict whether a sample will participate in a chemical reaction. Chemical properties may be used to classify compounds and find applications for them.

5. Temperature scales and conversions
Fahrenheit Celsius (SI system) ° F = 1.8(°C)+ 32 ° C = (5/9)(°F-32) Kelvin (Absolute) Temperature scale K = ° C + 273
Temperature scales and conversions

6. Celsius Temperature Scale
The Celsius temperature scale “centigrade" scale ("consisting of or divided into 100 degrees.“)
Andres Celsius (Swedish; ) developed the centigrade scale for scientific purposes. 100 degrees between freezing point (0˚C) & boiling point (100˚C) of pure water at sea level.
An international conference on weights and measures voted to name the centigrade scale after its inventor in

7. The Kelvin scale
Based on the Celsius scale, but has no negative numbers. Zero on the Kelvin scale is considered to be absolute zero; that is, the point at which all-molecular motion stops. K = °C + 273
