It is often seen as linked to the quest to turn lead or another common starting material into gold, [5] though in ancient times the study encompassed many of the questions of modern chemistry being defined as the study of the composition of waters, movement, growth, embodying, disembodying, drawing the spirits from bodies and bonding the spirits within bodies by the early 4th century Greek-Egyptian alchemist Zosimos. The current model of atomic structure is the quantum mechanical model. This matter can be studied in solid, liquid, or gas statesin isolation or in combination. The interactionsreactions and transformations that are studied in chemistry are usually the result of interactions between atoms, leading to rearrangements of the chemical bonds which hold atoms together.

But, they don't realize that knowing chemical reactions can help out in every day life. For example, if you are boiling fresh eggs you might have noticed that the shell will stick to the egg when you try to peel them compared to older eggs. That's because old eggs have a higher pH which toughens the skin under the shell and makes it stick better to the shell and therefore easier to lift off.

If you add baking soda or something else that's edible to the water of fresh boiling eggs it will increase the pH and make them easier to peel. Anyone who has taken enough chemistry to understand pH will be able to figure this out.

For me, I hated the chemistry homework and the theory, but I loved doing experiments. I had a great teacher who was always setting up elaborate experiments for us to marvel at, like making the liquid in a test tube go through all the colors of the rainbow. I guess you've just got to find what works for you in terms of learning and work with that.

I think anyone can learn chemistry as long as they get the right environment. And as it says in the article, chemistry is involved at every level of our society, so it's worth knowing the basics.

Not because it was science based I loved biology but because I didn't like having to do chemical experiments. I didn't have much confidence in myself back then and I guess I thought I would end up smashing the glass somehow or spilling the chemicals.

I eventually had to take a bridging course in chemistry in order to study biology at university and it turns out that chemical theory is really interesting. I still don't really like the physical side of things as in the test tubes, not physical chemistry!

Georgesplane Post 2 Anon Do not quote me on this because I am not exactly sure, but Butane should remain a solid if the air temperature is extremely low. Butane is only a solid when temperatures are below or so degrees Fahrenheit.

I think if the air temperature rises above this you will begin to see the butane turn to liquid.

Butane will remain a liquid under pressure or until it reaches its boiling point. At about thirty degrees Fahrenheit, liquid butane begins to boil turning to a gas.Chemistry is the science of matter.

This may sound simple, but chemistry is a complex and broad topic that broaches a wide variety of fields. From the core of the earth to the farthest reaches of.

Chemistry is the study of matter: its composition, properties, and reactivity. This material roughly covers a first-year high school or college course, and a good understanding of algebra is helpful.

What is chemistry

Chemistry is frequently defined as the study of matter and the reactions that matter undergoes. Actually, physicists, geologists, and biologists also study matter, but only chemists study the .

What is chemistry

Chemistry is the study of matter, its properties, how and why substances combine or separate to form other substances, and how substances interact with energy. Many people think of chemists as being white-coated scientists mixing strange liquids in a laboratory, but the truth is we are all chemists.

Chemistry is the study of matter and energy and the interactions between them. This is also the definition for physics, by the way. Chemistry . An important point to remember is that chemistry is a science, which means its procedures are systematic and reproducible and its hypotheses are tested using the scientific method.

Chemists, scientists who study chemistry, examine the properties and composition of matter and the interactions between substances.
