Question 554: 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.
