Even if the friction were totally eliminated, a heat engine still could not convert heat completely into work and be 100 percent efficient. Instead, the efficiency of an internal combustion engine depends on the difference in the temperature of the burning gases in the cylinder and the temperature of the burning gases in the cylinder and the temperature of the air outside the engine.

No, eliminating friction alone won't make a heat engine 100% efficient. While reducing friction can improve efficiency, there will still be losses due to other factors like heat exchange with the surroundings. The second law of thermodynamics states that it is impossible to have a heat engine with 100% efficiency.

What is the force that prevents all machines from being 100 percent efficient?
One reason for this is friction, which results in energy loss due to heat production. Additionally, there are inefficiencies in the conversion of energy from one form to another, such as from mechanical to electrical energy. Finally, external factors like air resistance can also contribute to reducing the overall efficiency of machines.
Explain why power plants are never 100 percent efficient?
Power plants are never 100 percent efficient because energy is lost in the form of waste heat during electricity generation. This waste heat is a byproduct of the conversion of fuel to electricity, and it cannot be completely avoided. Additionally, no machine or process can operate without some level of friction or resistance, which also contributes to efficiency losses.
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 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.
If a machine was 100 percent efficient how would the AMA compare to the IMA?
If a machine was 100 percent efficient, the AMA would be equal to the IMA. This is because in an ideal scenario where the machine loses no energy to friction or other factors, the AMA (actual mechanical advantage) would be the same as the IMA (ideal mechanical advantage).
Why are no machines 100 percent efficient?
Some energy is lost to friction.
Why aren't machines 100 percent efficient?
becaus ethey have friction
Explain why machines are not 100 percent efficient?
because they are not proper
What are some reason that machines are not 100 percent efficient?
friction and entropy the production of heat with in a system
What force stops machines from being 100 percent efficient?
One major factor that limits the efficiency of machines is friction. Friction creates resistance as moving parts come into contact with each other, leading to energy losses in the form of heat. Additionally, other factors such as air resistance, electrical resistance, and imperfections in materials can also contribute to reducing the overall efficiency of machines.

What furnace is 98 percent efficient?
Lennox top o the line furnace is 98.2 percent efficient
Why does friction stops machines from not being 100 percent efficient?
Because friction causes a dissipation of heat energy and other kinetic energy. If you use the equation f = ma (Newton's law), where f= force, m= mass; a= acceleration, you can apply this to any machine and factor friction into the mass x acceleration equation. it will always decrease hypothetical force when applied with friction.

Is it better for a machine to be 25 percent efficient or 75 percent?
75 %

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.
