Absolute zero is the temperature at which a thermodynamic system has the lowest energy. The notion that there is an ultimately lowest temperature was suggested by the behaviour of gases at low pressures: it was noted that gases seem to contract indefinitely as temperature decreases. It appeared that an “ideal gas” at constant pressure would reach zero volume at what is now called the absolute zero of temperature.

The calorific value is the total energy released as heat when a substance undergoes complete combustion with oxygen under standard conditions. It is typically expressed in joules per kilogram.

Asphalt, also known as bitumen, is a sticky, black, and highly viscous liquid or semi-solid form of petroleum. The primary use (70%) of asphalt is in road construction, where it is used as the glue or binder mixed with aggregate particles to create asphalt concrete. Its other main uses are for bituminous waterproofing products, including production of roofing felt and for sealing flat roofs.

Acceleration is the rate of change of velocity of an object with respect to time. An object's acceleration is the net result of all forces acting on the object, as described by Newton's Second Law. The SI unit for acceleration is metre per second square (m/sec2).

A piezometer is either a device used to measure liquid pressure in a system by measuring the height to which a column of the liquid rises against gravity, or a device which measures the pressure of groundwater at a specific point.

The Nag missile is an Indian third generation "fire-and-forget" anti-tank guided missile. It is an all weather, top attack missile with a range of 3 to 7 km. It is being developed by India's Defence Research and Development Organisation (DRDO) under the Integrated Guided Missile Development Program and is manufactured by Bharat Dynamics Limited. It is regarded as one of the best anti-tank guided missile.The speed of this missile is 230 metres per second.

The Hypothalamus is a portion of the brain that contains a number of small nuclei with a variety of functions. One of the most important functions of the hypothalamus is to link the nervous system to the endocrine system via the pituitary gland. The hypothalamus is responsible for the regulation of certain metabolic processes and other activities of the autonomic nervous system.

The atomic number or proton number (symbol Z) of a chemical element is the number of protons found in the nucleus of every atom of that element. The atomic number uniquely identifies a chemical element. It is identical to the charge number of the nucleus.

Male is the densely populated capital of the Maldives, an island nation in the Indian Ocean. It's known for its mosques and colorful buildings. It is also one of the most densely populated cities in the world.

The Kisan Credit Card (KCC) scheme is a credit scheme introduced in August 1998 by Indian banks. This model scheme was prepared by the National Bank for Agriculture and Rural Development (NABARD) on the recommendations of R.V.GUPTA committee to provide term loans and agricultural needs. Its objective is to meet the comprehensive credit requirements of the agriculture sector by giving financial support to farmers.
