What are the four main types of petroleum?

Very Light Oils / Light Distillates, Light Oils / Middle Distillates, Medium Oils, Heavy Fuel Oils

Explanation:

1) Very Light Oils / Light Distillates

- Jet Fuel

- Gasoline

- Kerosene

- Light Virgin Naphtha

- Heavy Virgin Naphtha

- Petroleum Ether

- Petroleum Spirit,

- Petroleum Naphtha

(2) Light Oils / Middle Distillates

- Most Grade 1 and Grade 2 Fuel Oils

- Diesel Fuel Oils

- Most Domestic Fuels

- Light Crude Marine Gas Oils.

(3) Medium Oils

- Most of the crude oil on the market these days falls into this category

(4) Heavy Fuel Oils

- Heavy crude oils

- Grade 3,4,5 and 6 Fuel Oils

- Heavy Marine Fuels

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
