Distillation is a process of separating components of a mixture based on their boiling points.

• It involves heating the mixture to vaporize the more volatile component

• The vapor is then condensed and collected as a separate liquid

• Commonly used in the production of alcoholic beverages, fuels, and chemicals

Distillation is a process used to separate components of a mixture based on their boiling points.

• Used in petroleum refining to separate crude oil into different fractions

• Used in the production of alcoholic beverages to separate ethanol from water

• Used in the chemical industry to purify solvents and separate different chemicals

• Can be used in the purification of water

• Can be used in the separation of air into its component

Heat exchangers are devices used to transfer heat between two or more fluids.

Bubble point and dew point are two important concepts in thermodynamics used to describe the behavior of a mixture of liquids and gases.

• Bubble point is the temperature at which a liquid mixture starts to boil and form bubbles of vapor.

• Dew point is the temperature at which a vapor mixture starts to condense and form droplets of liquid.

• Bubble point and dew point are related to each other through the vapor-liquid equilibr...read more

Chemical and Biological Oxygen Demand are measures of water quality and indicate the amount of oxygen required to break down organic matter.

• Chemical Oxygen Demand (COD) measures the amount of oxygen required to oxidize organic and inorganic matter in water.

• Biological Oxygen Demand (BOD) measures the amount of oxygen required by microorganisms to break down organic matter in water.

• COD is a faster test and measures both ...read more

Name mangling is a technique used by compilers to give unique names to functions and variables to avoid naming conflicts.

• Name mangling is used in C++ to support function overloading.

• It is also used in Python to avoid naming conflicts in modules.

• Name mangling can make it difficult to access variables and functions from outside the class in which they are defined.

• In C++, name mangling can be seen by using the 'nm' comman
