Ventilation systems let warm air out of a building. Exhaust air heat pumps pick up the warm air, and heat fresh air coming into the building, or even heat water. Exhaust air heat pumps can be used to heat water, and heat houses or apartments. They work in the same way as air and ground […]

Class 11, Conservation of energy, IIT JEE, Physics, Work, Energy, and PowerDissipation of energy involves how energy is wasted in a reaction or transformation. A form of energy that is not transferred or converted to useful energy is considered wasted because it is lost and dissipated to the surroundings. As we know, no system is perfect. When a system changes, energy is dissipated. This dissipated energy

Class 11, Conservation of energy, IIT JEE, Physics, Work, Energy, and PowerIntroduction We know from the law of conservation of energy in a closed system, that is a system which is isolated from its surroundings, the total energy of a system is always conserved.” The conservative force obeys the law of conservation of energy. Conservative and non – conservative forces are the two types of forces.

Class 11, Conservation of energy, IIT JEE, Physics, Work, Energy, and PowerUsing an air-source heat pump, heating and cooling your house is a great idea. It can give up to three times more thermal energy to a home than it takes in through electricity. It’s possible because a heat pump moves heat instead of making it from fuel, unlike a combustion heater. Air-source heat pumps have

Class 11, Conservation of energy, IIT JEE, Physics, Work, Energy, and PowerYou require energy to perform a task. This requirement comes in a variety of forms. Chemical energy is the energy released by chemical substances when they undergo a reaction and evolve into something else. The breaking and remaking of a bond requires energy, which can be absorbed or released by a chemical system. It’s a
Introduction Energy is a property of physics that must be transferred to a physical system or a body to work on and/or heat it. Movement is simply the result of energy. Energy is a conserved quantity. The law of conservation of energy states that energy cannot be created or destroyed. Energy can be transformed into

Class 11, Conservation of energy, NEET, Physics, Work, Energy, and PowerThe energy within a system is not maintained by a nonconservative force, but is instead released out of the system. As a result, these forces are often referred to as dissipative forces.When the path is a closed loop, the total work done by a conservative force is independent of the path that results in a

Class 11, Conservation of energy, NEET, Physics, Work, Energy, and PowerConservative force is the force applied to move a particle from one point to another. It is not dependent on the path taken by the particle. It only depends on two factors: the initial and final positions of the particle. The conservative force is responsible for the orderly motion of particles and atoms in a

Class 11, Conservation of energy, NEET, Physics, Work, Energy, and PowerWork done by a conservative force is defined as the work done by a body when it is in equilibrium with a conservative force acting upon it. In contrast to work done by a body when it is in equilibrium with a non-conservative force, work done by a conservative force is known as static work.

Class 11, Conservation of energy, NEET, Physics, Work, Energy, and PowerPower The rate at which energy is transported or converted, or the rate at which labour is performed, is referred to as power. It is the quantity of work completed per unit of time in technical terms. Watt (W), or joules per second (J/s), is the SI unit of power. Horsepower (Hp), which is roughly
