What is the difference between a chemical process and a physical process in chemistry?
Physical and chemical processes can be classified by the changes occurring on the molecular level. In general, chemical processes involve changes in chemical bonds, while physical processes involve changes only in intermolecular forces.

See lessWhat is it about the ocean that makes it look blue when it reflects the sky?
The ocean is blue because water absorbs colors in the red part of the light spectrum. Like a filter, this leaves behind colors in the blue part of the light spectrum for us to see. The ocean may also take on green, red, or other hues as light bounces off of floating sediments and particles in the waRead more

See lessHow does tomato juice make skunk smell go away?
Tomato juice does not make skunk odor go away. More specifically, tomato juice does not react chemically with the skunk odor to destroy it. Instead, it simply has a strong enough smell on its own to partially mask the skunk smell. But in this respect, it is no different from any other strong odor.

See lessHow does plasma make a campfire flame orange?
The de-excitation of plasma (charged gas) is not the source of the light given off by a campfire's flame. The incandescence of solid soot particles billowing up on an updraft of hot air is what creates the light seen as a flame.

See lessHow does dissolving a salt molecule in water make its atoms ionize?
Dissolving a salt molecule in water does not make its atoms ionize. The atoms in solid salts are already ionized long before touching water.

See lessHow do I know if something is an acid so I can avoid eating it?
A food with a pH below 4.6 is high in acid. This includes many citrus fruits, plums, grapes, pomegranates, and several other fruits. Tomatoes, which are technically a fruit, are also acidic. The pH value tells you if something is an acid, a base, or neutral.

See lessHow can glass be a liquid if it's so hard?
Glass is not a liquid in the strictest sense of the word. But it is also not a standard solid. The chemistry of glass is complex and research is ongoing, but the current consensus is that glass is a phase of matter all its own, known as an "amorphous solid".

See lessCan you light diamond on fire?
YES, you can. Although diamond requires a higher temperature to burn, it does indeed burn via normal carbon combustion. You can even burn diamond in a regular flame if you are patient and conditions are right. To accelerate the burning of diamond, you can give it more heat and more oxygen
