What is the energy lost formula used to calculate the amount of energy dissipated in a system?
The energy lost formula used to calculate the amount of energy dissipated in a system is: Energy Lost Initial Energy - Final Energy.
How can one determine the amount of energy lost in a system and identify ways to minimize it?
To determine the amount of energy lost in a system, one can calculate the difference between the input energy and the output energy. Ways to minimize energy loss include improving insulation, using energy-efficient equipment, and reducing unnecessary energy consumption.
How do you calculate how much mechanical energy is lost in a inelastic collision?
In an inelastic collision, mechanical energy is lost due to the deformation of the objects involved and the generation of heat or sound. The amount of mechanical energy lost can be calculated by taking the initial mechanical energy of the system before the collision and subtracting the final mechanical energy of the system after the collision. This energy loss is typically converted into other forms of energy such as thermal energy or sound energy.
What is meant by lost energy?
Lost energy refers to energy that is not efficiently utilized or is wasted during a process. It could be in the form of heat, sound, or other types of energy that do not contribute to the intended output of a system. Improving energy efficiency aims to reduce the amount of lost energy in various processes.
When energy is transformed is some lost or gained?
When energy is transformed, it can be neither lost nor gained according to the Law of Conservation of Energy. Energy can only change forms, such as from kinetic to potential, but the total amount of energy in a closed system remains constant.

How can we calculate the heat lost by the hot water in a given system?
To calculate the heat lost by hot water in a system, you can use the formula Q mcT, where Q is the heat lost, m is the mass of the water, c is the specific heat capacity of water, and T is the change in temperature. This formula helps determine the amount of heat energy transferred from the hot water to the surroundings.
How do you find the amount of mechanical energy lost when colliding with a floor?
To find the amount of mechanical energy lost when colliding with a floor, you can calculate the difference in kinetic energy before and after the collision. Subtract the final kinetic energy (which would be zero if the object comes to a stop) from the initial kinetic energy to determine the mechanical energy lost during the collision.

What does enthalpy measure and how is it related to the energy of a system?
Enthalpy measures the total energy of a system, including its internal energy and the energy required to maintain constant pressure. It is related to the energy of a system because changes in enthalpy reflect the amount of heat transferred during a process, indicating whether the system has gained or lost energy.
Does the amount of energy entering entering an ecosystem from the sun is equal to the amount of energy used by organisms plus the amount of energy lost as heat?
No, the amount of energy entering an ecosystem from the sun is greater than the amount of energy used by organisms plus the amount of energy lost as heat. This is known as the 10% rule, where only about 10% of energy is transferred from one trophic level to the next, with the rest being lost as heat.
When people say energy is lost what do they mean?
The energy in a closed system is constant, which is the principle of Conservation of Energy, but in machines the amount of useful energy coming out is less than the amount going in. This is explained by lost energy. In a petrol engine the lost energy comes out in the form of heat because the engine block is hot, which happens because of friction in the bearings but also because the gas in the cylinder has to be at a high temperature and pressure.
How much is mechanical energy lost?
Mechanical energy lost is usually due to factors such as friction, air resistance, or heat generation during processes. The amount of mechanical energy lost can vary depending on the system and its conditions, but efforts can be made to minimize these losses through efficient design and maintenance.
Is it true that when energy changes form some energy is always lost as sound?
When energy changes form, it may be converted into sound energy as a byproduct. However, not all energy transformations result in energy being lost as sound. The amount of energy "lost" as sound depends on the specific process and system involved.
