Element
Thermochemistry-
Study of transfers of energy as heat occurring during chemical and physical changes
Temperature (T)
Average kinetic energy of the particles in a sample; as it increases, so does the temp.
Heat (q)
Energy transferred between samples because of their difference in temp.; measured in Joules (J) with calorimeters
(High heat->low heat)
Specific heat
The amount of energy transferred during a temp.
Ionic compounds
First element & second element +IDE
Or gang
Covalent compounds
Prefix first element & prefix second element +IDE
Triple point
The temperature & pressure conditions at which the solid, liquid, & gas of a substance coexist
Critical pressure
The lowest temperature in which a substance can exist as a liquid
Standard pressure:
1.0 ATM 760 mmHg 760 Torr 101.3 Kpa 30.00 in 30'C 273'K
Organic compound
Study of compounds containing carbon except CO2
Inorganic
Study of compounds that aren’t organic
Physical chemistry
Study of changes of matter and their energy
