Surface tension is the phenomenon in which the surface of a liquid is strongly attracted to other similar liquids and to itself. This attraction allows the liquid to form a thin sheet or film that is highly resistant to rupture. It is caused by the cohesive forces between molecules of the same liquid. The surface …
Freezing of water occurs when the kinetic energy of the water molecules is reduced to the point that they can no longer overcome the attractive forces between the molecules. This causes them to become arranged into a more structured form, forming ice crystals. As the temperature decreases further, the water molecules will become more organized …

Heat capacity is the amount of energy required to raise the temperature of a given mass of a substance by one degree. The heat capacity of water is particularly high, due to its molecular structure. Water molecules have a strong attraction to each other and require extra energy to be separated and heated, thus requiring …
The boiling point of a substance is the temperature at which it changes state from liquid to gas. The boiling point of water is 100°C (212°F).The boiling point of water is 100°C (212°F) at normal atmospheric pressure. Boiling point can vary depending on the pressure of the surrounding environment. For example, at higher altitudes, atmospheric …

It is a major source of added sugar in the diet, and is associated with a higher risk of obesity, diabetes, and heart disease. 2. Artificial Sweeteners: Artificial sweeteners are sugar substitutes used in many …
Tartrazine is a yellow dye used to colour many food and drink products. It is added to products such as soft drinks, jams, jellies, ice cream, candy, cereal, sauces, and salad dressings. It is also used to colour cosmetics, medications, and other products. Tartrazine is approved for use in the United States, Canada, and the …
Soft drinks, also known as soda or carbonated drinks, are non-alcoholic beverages that contain carbonated water, a sweetener, and a flavouring. Popular brands of soft drinks include Coca-Cola, Pepsi, Sprite, Mountain Dew, and Fanta. Soft drinks are consumed in large quantities around the world, and are associated with various health risks due to their high …
1. Place a beaker containing 50 mL of water on a flat surface. 2. Add 2g of Sodium thiosulphate to the beaker and stir the solution. 3. Place a light source (like a torch or a lamp) at a distance of about 15-20 cm from the beaker. 4. Arrange a path for the beam of …

A colloid is a mixture of two substances, one of which is finely divided and dispersed evenly throughout the other. Examples of colloids include fog, whipped cream, and paint. A suspension is a mixture of two substances, one of which is larger and more dense than the other, and which settle out of the mixture …
