Factors Affecting Gas Solubility in Liquids
Here are the factors that affect the solubility of a gas in a liquid:
Physical Factors
- Temperature: An increase in temperature generally decreases the solubility of a gas in a liquid.
- Pressure: An increase in pressure generally increases the solubility of a gas in a liquid.
- Surface Area: An increase in the surface area of the liquid can increase the solubility of the gas.
Chemical Factors
- Polarity of the Liquid: Polar liquids tend to dissolve polar gases more

Homogeneous mixtures are uniform; that is, any portion has the same composition and properties. The blended components cannot be distinguished even with the aid of an electron microscope, which is the most powerful.
Homogeneous mixtures are also called solutions. Depending on the physical state of the mixture, solutions can be gaseous, liquid, or solid.
Gaseous Solutions
A set consisting of gases, such as the atmosphere, is made of 71% nitrogen, 21% oxygen, and 1% other gases.

Sugar Production: From Cane Cultivation to Crystallization
**Sugar: From Field to Table**
Sugar, also known as sucrose (C12H22O11), is a disaccharide composed of glucose and fructose. It is commonly referred to as table sugar. Sucrose is primarily obtained from sugar cane or beets. In industrial settings, the term “sugar” or “sugars” may refer to various monosaccharides and disaccharides, which generally have a sweet taste. However, by extension, it refers to all carbohydrates.
Sugar can caramelize when heated above its decomposition point, resulting in a

Mixtures
Mixtures are formed by joining two or more substances in various proportions, each retaining its own characteristics. There are different types of mixtures based on how the components are combined. If the components of a mixture cannot be distinguished with the naked eye, it is homogeneous. If the components can be differentiated, it is said to be heterogeneous.
Benchmark Optical
This method is used to classify mixtures and is based on direct observation or indirectly through a magnifying
