A World Without Chemistry A world without chemmistry would be simply disastrous.We would have no phones‚ no lightbulbs‚ no social networking! Almost everything we use in our daily lifes depends on chemistry to exist‚ from the food we eat to the clothes on our backs. If we had never studied chemistry we wouldn’t have liquid oxygen. This was developed in the 1800s and is now probably best-known for its role as rocket fuel. Without rockets the space race wouldn’t have happened‚ or all the everyday

Chemistry in everyday life : Our entire universe is made up of matter which is constantly changing forms and evolving into other forms of energy. Chemistry is defined as the study or science of this ever changing matter. The other sciences which we study commonly like biology‚ physics and mathematics are all dependent on chemistry and are known as specific studies under the elaborate subject of chemistry. Since there is chemistry seen in biological forms as well as physical states of nature‚ there

The pursuit of knowledge carried on by scientists for the past several centuries has produced results over which opinion is sharply divided. Science‚ originally intended to conquer and harness the forces of nature for the good of man‚ is looked upon by some as the chief cause of the suffering of humanity today. On’the other hand‚ there are a good many people who consider science to be the harbinger of all progress‚ prosperity and comfort. The contro¬versy has been raging for a long time‚ though science

in to account that honey is a more viscous liquid as compared to ink. Therefore the low viscosity of ink allows it to diffuse at a faster rate than honey in a solution. Q-9 Name two gases of air which dissolve in water by diffusion. What is the importance of this process in nature ? Carbon-di-oxide and Oxygen are the two atmospheric gases‚ that can diffuse in water. Oxygen is helpful for the animals inside the water and CO2 is helpful for plants in the water The oxygen from lungs diffuses into

northward through trade with their neighbors. It was probably the Maya‚ over 1500 years ago‚ who brought Cacao to Yucatan in what is now Mexico.
