The maximum efficiency of the carnot engine only depends on two factors:
1 - The temperature of the hot reservoir (TH)
2 - The temperature of the cold reservoir (TC)
And is given by (TH - TC) / TH « or » 1 - TC / TH So by that we can see the maximum efficiency (100%) would be when the difference of temperatures between the two reservoirs is infinite.
aluminium should lose three electrons to attain noble gas configuration
yes
Metals , generally, have electronic configuration: with outermost electron having 1,2 or 3. Since, they can easily attain noble gas configuration to attain stability; they readily loose electron.
It should loose 2 electrons to become a noble gas.
All should lose 2 electrons to attain the nearest noble gas configuration
It is impossible to achieve 100% efficiency in heat engines due to the second law of thermodynamics, specifically the Kelvin-Planck statement, which states that it is impossible for any device that operates on a cycle to receive heat from a single reservoir and produce an equivalent amount of work. Some amount of energy will always be lost as heat to the surroundings, limiting the maximum efficiency that can be achieved.
Some of the force used in a lever will be to overcome friction, this means that not 100% of the force can be used to lever as some of it will be used to overcome friction as well as an multitude of other forces.
Yes, it is possible and normal.
Yes, smiling is possible in each phase of life. It gives you positivity and helps you attain peace.
If one has a bad driving record, it is still possible to attain car insurance in the state of Virginia. The main problem is that you will end up paying a much higher premium.
A heat engine operating between 2 temperatures, Thot, the heat source, and Tcold, the heat sink, can be 100% efficient only when Tcold is absolute zero. Carnot worked out the equation to determine the best possible efficiency of a heat engine designed to produce mechanical energy ("Work") from heat energy: Wout = (Heat Energy in at Thot) x (Thot - Tcold)/(Thot) Note that (Thot - Tcold)/(Thot) is 1 only if Tcold is zero. In every other case, the ratio is less than 1. The amount of heat energy discharged to the heat sink at Tcold is: (Heat Energy in at Thot) - Wout. (You can work this out from the equation. It reflects the law of conservation of energy. ) This just means that all the heat energy absorbed by the heat engine is converted into either mechanical energy or heat energy at a lower temperature. No energy is lost and no extra energy is created. "Efficiency" according to Carnot's equation tells us the best possible ratio between these two energy outputs that nature allows a heat engine to achieve. You can think of a heat engine as a device that splits an amount of heat energy at some high temperature into mechanical energy and heat energy at some lower temperature.

attain means accomplish.EXAMPLE:I want to attain knowledge.
Yes, it is still possible for a male to enter puberty at 16 or 17 years of age. It is unlikely, buy possible, as all guys develop at different ages.
No.To explain requires many years of education
The suffix of "attain" is "-tain."
Only if you are a photon. In that case, you always move at the speed of light. If you're not a photon, and have any mass while you're sitting still, and are not moving at the speed of light right now, then you can never attain light speed.
If you work hard, you can attain your goals. She will attain the highest honor we can bestow.
