2. Flame
Chemistry isn’t just in factories or labs, but it is omnipresent in every sphere of life. Furthermore, taking chemistry as a subject enhances our ability to apply chemistry in our daily lives.
For ex, in the initial classes at lab we learn how the color of the flame tells us how much air is available to the burner. If the flame is yellow it shows that there’s a small amount of air, whereas if the flame is blue it shows there’s sufficient air.

3. Likewise, the same principle can be applied when we are cooking in the kitchen. If we notice yellowish flames blowing out from the cooking range, we know it means the air valves are blocked and the fuel is getting wasted. This signals us that the cooking range needs cleaning and repairs.
This example highlights how chemistry helps us identify and fix simple issues in our daily lives on our own, and helps us be independent and self-reliant.

4. Many of the changes and variances you observe in the world around you are caused by chemical reactions.
Knowing some chemistry can help you make day to day decisions that affect your life.
E.g. knowing what to mix with what , and if it would cause a reaction or an affection.

5. Chemistry made us realize that things have an expiry date , and that it is important to watch out for eating expired food.
IN MEDICINE:
The abolition of disease and major contribution to many improving human wealth, have been made by the modern chemical discoveries.

6. Chemistry is an important science involved in the transformation of matter.

7. NaCl = Table Salt Salt-a chemical compound
It is fascinating to know that salt, a compound we eat everyday, is made up of two substances, sodium and chlorine.
NaCl = Table Salt

8. Why meals are cooked faster in a pressure cooker?
A Pressure Cooker is like any other pot but it has a more elaborated lid that seals the pot completely. When you heat water inside the pot it boils and the steam cannot escape, so it remains inside and starts to build up pressure. Under pressure, cooking temperatures raise much higher than under normal conditions (higher than the boiling point of water, that is 100ºC), so then the food is cooked much faster. Cooking times can be reduced by a factor of three or four.

9. Chemistry Around the House
Something as simple as Toothpaste involves at least three chemicals, if not more. It is the mixture of fluoride, peroxide and baking soda and its chemical reaction that keeps your teeth clean. From this course I got to know how to read the chemicals composition.

10. Gases Inside The Diving Cylinders
A Diving cylinder, scuba tank or diving tank is a gas cylinder used to store and transport high pressure breathing gas as a component of a scuba set. It provides gas to the scuba diver through the demand valve of a diving regulator.

12. Scuba Tank Gases
1. Nitrox - Nitrox is basically a mixture of nitrogen and oxygen. This particular "breathing gas" mixture is used by scuba divers who dive to a depth of up to 130 ft only.
2. Heliox - Heliox combines both oxygen and helium in the tank.
3. Hydreliox - Hydreliox combines oxygen, helium and hydrogen in the scuba diving tank. With Hydreliox in their tanks, scuba divers can safely pursue diving depths of up to 400 feet.

13. 4. Trimix - Trimix uses oxygen, nitrogen and helium as the "breathing gas" for scuba diving. Trimix is most commonly encountered in dives where there is a large risk of either oxygen toxicity or nitrogen narcosis. This is most common among deep scuba diving treks. The helium is specifically added to the mix of nitrogen and oxygen in order to counter the partial pressure potential of nitrogen and oxygen at such great depth.

14. We are living our life and chemistry is in every part and moment of our life. We must realize the importance of chemistry in our daily life. From waking up in the morning to the time of sleeping, chemistry moves with us like our shadow and even while we sleep, chemistry is there with us. When we walk, when we take food, when we breathe, when we bath, when we drink, when we do any work that we do in our everyday life, everywhere and every time, chemistry is always with us. I learned from this course too many things such as our body; we know what are the elements and compounds.Elements are the smallest substances and compounds are combination of elements . And our body is made up of millions of compounds. Every part of our body, tissues, veins, blood molecules are made up of compounds. All that we observe in our surroundings contains chemistry, everything contains chemistry. That is the main reason why chemistry is so much important in our daily life.
