LPG Full Form
LPG stands for Liquefied Petroleum Gas, a flammable mixture of hydrocarbon gases—primarily propane and butane—used as fuel for cooking, heating, and vehicles, stored and transported in liquid form under moderate pressure in steel cylinders or tanks. At normal atmospheric pressure and temperature, these gases exist in gaseous state, but when subjected to moderate pressure (typically 2-8 atmospheres) or slight cooling, they liquefy, reducing their volume by approximately 250 times,

Sunrise Time
Sunrise time varies significantly based on your geographical location (latitude and longitude), the date (time of year), and your time zone, making it impossible to provide a single universal answer without specifying these parameters. In general, sunrise occurs when the upper edge of the sun appears above the horizon in the morning, with timing determined by Earth's rotation and its orbital position around the sun. For locations in India, sunrise typically ranges from approximately 5:00 AM t

Earth's Atmosphere Layers
Earth's atmosphere is divided into five distinct layers based on temperature variations with altitude: the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The troposphere is the lowest layer, extending from Earth's surface to approximately 8-15 kilometers (varying by latitude and season), where all weather phenomena occur and temperature decreases with altitude at about 6.5°C per kilometer. This layer contains roughly 75% of the atmosphere's mass and nearly all water v

Distinguish
To distinguish means to recognize, identify, or perceive the differences between two or more things, concepts, people, or ideas based on their distinctive characteristics, features, or qualities.

Rhombus
A rhombus is a quadrilateral (four-sided polygon) where all four sides have equal length, making it a special type of parallelogram. Key properties of a rhombus include: opposite sides are parallel, opposite angles are equal, diagonals bisect each other at right angles (90 degrees), diagonals bisect the opposite angles, and the sum of adjacent angles equals 180 degrees. While a square is a special type of rhombus where all angles are 90 degrees, a rhombus generally has angles that are not rig

National Language of India
India does not have a single national language—this is a common misconception. Instead, the Constitution of India recognizes Hindi in the Devanagari script as the official language of the Union Government, while also granting official status to English for official purposes.
