Question 502: Thermodynamics & KTG

Question

Even Carnot engine cannot give $100\% $ efficiency because we cannot

Accepted Answer

$\eta  = 1 - {{{T_2}} \over {{T_1}}}$
For $\eta  = 1$ or $100\% $, ${T_2} = 0K.$
The temperature of $0$ $K$ (absolute zero) can not be obtained.

Answer

prevent radiation

Answer

find ideal sources

Answer

reach absolute zero temperature

Answer

eliminate friction.
