Perhaps you could clarify the question? A generalized statement: nothing is ever 100% efficient. The reason for this is that the energy is converted into many different parts of the process, i.e. thermal, mechanical, dissipation, etc. The statement "all matter is conserved" applies to this case as well, despite not achieving 100% efficiency in what you need, no matter is ever lost. It is simply converted from one state into another.

A nice example is the melting, and evaporation of water. Here, solid turns to liquid, and from liquid it goes into a gaseous phase, whereupon you no longer see any water, however it still remains as water vapor, only we cannot visualize it.

What temperature is required to transfer waste heat to the environment for a heat engine to be a 100 percent efficient?

In order for a heat engine to be 100 percent efficient, the temperature of the cold reservoir where waste heat is transferred should be absolute zero (0 Kelvin). This is not achievable in practice, as it violates the second law of thermodynamics.


What temperature is required to transfer waste heat to the environment for a heat engine to be 100 percent efficient?

A heat engine can never be 100% efficient due to the second law of thermodynamics, which states that some heat energy will always be lost to the surroundings. The temperature required for maximum efficiency is the temperature of the heat source for the engine. The efficiency of a heat engine is determined by the temperature difference between the heat source and the environment.


Is a nuclear generator 100 percent efficient?

No, nuclear generators are not 100 percent efficient. They typically have an efficiency rate of around 30-40%, which means that 30-40% of the energy from the nuclear reactions is converted into electricity, while the rest is lost as heat.


Why is a machine always less than 100 percent efficient?

Machines are never 100% efficient due to factors such as friction, heat loss, and mechanical limitations. Some amount of energy will always be lost during the transfer or transformation process, making it impossible for a machine to achieve perfect efficiency.


Can a machine ever be 100 percent efficient?

No, a machine can never be 100 percent efficient due to various factors such as friction, heat loss, and other sources of energy dissipation. These factors inevitably lead to some level of energy loss, making perfect efficiency unattainable in real-world machines.

Why may an electrical heater be 100 percent efficient?

An electrical heater can be 100 percent efficient because all of the electrical energy provided to the heater is converted into heat. This occurs when there are no energy losses due to factors such as resistance in wires or inefficient components within the heater.


What are some reason that machines are not 100 percent efficient?

Are electric heaters 100 percent efficient?

No, electric heaters are not 100 percent efficient. While they convert all the electricity they consume into heat, some heat can still be lost through the material of the heater itself, especially if it is not well insulated. Also, some heat may escape into the surrounding environment instead of heating the intended space.

Why 100 percent heat not convert in mechanical work in engine?

No engine is 100% efficient: there is always some loss of energy between input and output.

What is a device that uses heat to do work and but is not 100 percent efficient and expels excess heat?

A common device that fits this description is a combustion engine, such as those found in cars. These engines convert the heat generated from burning fuel into mechanical energy to do work, but they are not 100% efficient and expel excess heat through the exhaust system.


Can a device be 100 percent efficient when it comes to heat transfer?

Only if you're referring to an electric heater ... since all loses are also heat. The real world answer is no.


Why power plant are never 100 percent efficient?

Power plants are not 100% efficient because some energy is lost in the form of heat during the generation and transmission of electricity. This loss occurs due to factors such as friction, resistance in the electrical lines, and limitations in converting heat to electricity. Additionally, no machine or system can operate without any losses due to the laws of thermodynamics.
