Why thermos flask does not let the heat escape?
It is especially designed to reduce heat transfer through conduction, convection, and radiation. A vacuum between two layers reduces the heat transfer through conduction and convection; the fact that the surfaces are mirror-coated also reduces losses through radiation.
How can you save thermal energy?
There is no way to save thermal energy in the long term; heat tends to escape. You can reduce the losses by some isolation measures, as those used in a thermos bottle.There is no way to save thermal energy in the long term; heat tends to escape.

What are energy losses?
Energy losses refer to the energy that is not efficiently transferred or converted into usable energy in a given system or process. The causes of energy losses can include factors such as friction, heat dissipation, and inefficiencies in energy conversion mechanisms. Minimizing energy losses is important for improving the overall efficiency and sustainability of energy systems.
What is thermal energy loss?
Thermal energy loss refers to the transfer of heat from a warmer object to a cooler one in the surrounding environment. It can occur through processes like conduction, convection, and radiation. Insulating materials and proper building design can help reduce thermal energy loss.
What causes usable energy to be lost when you heat your house?
Usable energy is lost when you heat your house due to heat transfer mechanisms like conduction, convection, and radiation. Inefficiencies in insulation, air leakage, and heating equipment can also contribute to energy losses. Additionally, differences in indoor and outdoor temperatures lead to heat transfer, resulting in energy wastage.

In large long distance power lines is the power sent at very high voltages or as very large currents?
high voltage - this minimizes I^2*R losses (losses due to the inherent resistance of the wire).

What is the relationship between energy input energy output and energy losses whenever transfer of energy takes place?
Energy input = energy output + losses. Both energy output and losses are usually positive (they might also be zero in some specific cases), meaning that (usually) each of them individually is less than the energy input.
What is the relationship between energy input and energy output and energy losses whenever transfer of energy takes place?
Energy input is the total amount of energy supplied to a system, energy output is the useful energy that is obtained from the system, and energy losses refer to the energy that is dissipated and not used for the intended purpose. In any energy transfer process, some energy will be lost as waste heat due to inefficiencies, friction, or other factors. The relationship between them can be described by the energy conservation principle, where energy input equals energy output plus energy losses.
Why is some of the thermal energy produced by the furnace lost to the outside air?
Thermal energy is lost to the outside air due to conduction, convection, and radiation. Heat energy naturally flows from a higher temperature region to a lower temperature region, so the furnace loses some of its thermal energy to the cooler surrounding environment. Adequate insulation and sealing can help minimize these losses.
What percentage of energy is converted into useful energy?
It depends on the efficiency of the machine. No machine is perfect and there are always losses and waste. Usually the losses are a greater percentage than the useful energy.
Why does magma cool?
Magma cools because it losses heat to its surrounding environment, either due to convection or contact process.
Why do solids conduct heat best?
Solids conduct heat best because their particles are closely packed together, allowing for efficient transfer of thermal energy through direct contact. This facilitates the transfer of vibrations and kinetic energy from one particle to another, leading to effective heat conduction. Additionally, the lack of easily deformable spaces in the solid structure minimizes energy losses compared to fluids or gases.
