Energy in industry and living things

2. TYPES OF ENERGY
• 1. KINETIC ENERGY
• 2. HEAT ENERGY
• 3. ELECTRICAL ENERGY
• 4. POTENTIAL ENERGY
• 5. LIGHT ENERGY
• 6. NUCLEAR ENERGY
• 7. RADIATION
• 8. CHEMICAL ENERGY
• 9. SOLAR ENERGY

3. 1. KINETIC ENERGY
Gas molecules are mobile molecules.
Light molecules move faster
2. HEAT ENERGY
Physical changes : heat of …..
Chemical changes : Bond dissociation enthaply – Bond formation enthalpy

4. 3. ELECTRICAL ENERGY 4. POTENTIAL ENERGY
Electrolysis

5. 5. LIGHT ENERGY 6. NUCLEAR ENERGY
Protons and neutrons are held together by nuclear energy

6. 7. RADIATION 8. CHEMICAL ENERGY 9. SOLAR ENERGY
In nuclear rxns energy is
released in the form of
radiation.
X  Y + Z + energy
X : Heavy unstable nucleus
Y & Z : lighter nuclei

17. PETROLEUM PRODUCTS

18.  cleaning fluids
 paint and varnish diluents
 asphalt diluents
 rubber industry solvents
 cigarette lighters
 portable camping stove and lantern fuels.

19. • product of styrene and polystyren plastics
• pesticides

22. CLASSIFICATION OF COMPOUNDS

23. ORGANIC COMPOUNDS
• CHEMISTS IN THE EARLY NINETEENTH CENTURY
KNEW THAT LIVING THINGS, SUCH AS THE
PLANTS AND PANDA PRODUCE AN IMMENSE
VARIETY OF CARBON COMPOUNDS. CHEMISTS
REFERRED TO THESE COMPOUNDS AS ORGANIC
COMPOUNDS BECAUSE THEY WERE PRODUCED
BY LIVING ORGANISMS.

24. • THE SIMPLEST ORGANIC COMPOUNDS ARE HYDROCARBONS,
WHICH CONTAIN ONLY THE ELEMENTS CARBON AND HYDROGEN.
Hydrocarbons

25. Molecular Structure Of Hydrocarbons
• ALKANES
• CYCLOALKANES
• ALKENES
• ALKYNES
• AROMATIC HYDROCARBONS

26. ALKANES (single bond)

27. ALKYL GROUPS

28. CYCLOALKANES

29. ALKENES (DOUBLE BOND)

30. ALKYNES (TRIPLE BOND)

31. ADDITION OF HYDROGEN TO
ALKENES & ALKYNES

32. AROMATIC HYDROCARBONS

36. COMBUSTION REACTIONS OF
HYDROCARBONS
