There are both chunky and smooth kinds of peanut butter available in the market. However, the creamy textured one is largely preferred over the chunky type. The peanut butter is made of peanut oil and very finely ground peanuts. Since the ground peanuts are so fine, our tongue is unable to feel their individual textures […]

Chocolate, in its basic form, is composed of cocoa powder, cocoa butter and some type of sweetener such as sugar; however, modern chocolate includes milk solids, some added flavours, modifiers and preservatives. The fat in cocoa beans (called cocoa butter) melts in a small temperature range, between 93 and 100 degrees Fahrenheit (34 to 38

Salt is basically made with sodium and chlorine atoms joined together. However, almost all kinds of salts have different textures due to their manufacturing styles and origins. Sea salt is often less ground, whereas table salt or refined salt is dried in extreme high temperatures and then processed. This alters it from its original state.

Cutting onions is like unleashing a series of chemical reactions. When we cut the onion, the onion molecules transform into a gas that is sulphuric in nature. As soon as this gas comes in contact with our eyes, it transforms into small amounts of sulphuric acid which itches, burns and brings tears to our eyes.

Plain water when boiled will never boil over the edge of the pot, because the bubbles will pop before they reach the surface. By adding olive oil to the boiling water, the surface tension is interrupted, thereby preventing the water from foaming up and boiling over the pot. By adding oil to the water, the

We need to eat food to get the nutrients needed for maintaining a healthy body. Food gives us energy for doing our work, for growing and maintaining other body functions such as digestion, producing body heat and even for breathing. We need food to produce material for the growth and repair of the body and

Calcium is a very important mineral that gives us healthy bones and teeth. Apart from this, it helps muscles contract, helps blood clot, controls blood pressure and helps prevent gum disease. Calcium is important for a lot of other body functions in addition to the absorption of vitamins. We lose calcium every day through our

Chemicals are the basic building blocks of all things in this world. Food items consist of chemical compounds that are largely harmless and most often desirable. Nutrients like carbohydrates, proteins, fat and fibre are also chemicals. Most of these nutrients are produced naturally and without any intervention from humans. They contribute in providing us with

A substance dissolves if the attraction between the particles of the solute and the solvent is enough to overcome the attraction of the particles of each substance for the others of the same type. The attraction between ions in table salt and water molecules is enough to pull both individual ions away from the salt

Foam is a dispersion of particles in a continuous medium. The particles are the gas bubbles and the medium is a liquid. When chemical reactions release gas, the chemicals foam up. Just like while baking soda and vinegar are combined, they produce foam. Baking soda releases carbon dioxide that makes carbonic acid when mixed with

Ice floats because it is less dense or has less mass per unit volume than water. Water molecule, due to its strong covalent bonds between the oxygen atom and hydrogen atoms in it, makes it denser than ice. Water reaches its maximum density at 4º C (40º F). As soon as water converts to ice,

By putting salt on the icy roads, the freezing point of water is being altered. Water with higher salinity has a lower freezing point than water that does not have salt. By salting the roads, the freezing point of water that forms ice is lowered, which further results in melting and preventing water, rain or

The two primary factors that control the melting of the snow are the sun’s intensity and air temperature. It melts from the top to the bottom. With the sun’s heat or increase in temperature, the snow crystals start breaking down. With the shift in equilibrium between snow and the cold temperature, there is a change

No air balloon is airtight, which means that the air molecules can escape through the surface or leak through the knot. The surface of the balloon is made of latex rubber, which keeps the air in for some time. However, when the balloon is inflated with air, its skin stretches becoming so thin in some

The Dead Sea is a salt lake that is located at the lowest elevation on land and one of the saltiest lakes on the earth. It is 9 times as salty as the ocean. It is because of its extremely high salinity which makes its water very dense, more than the density of the human
