Question

a carnot engine oprates between 400 k and 500 k its effiency is

Answer 1

Answer:-

$\pink{\bigstar}$ Efficiency [η] is 20%.

• Given:-

A Carnot Engine operates between = 400 k and 500k

• To Find:-

Efficiency [η] = ?

• Solution:-

We know,

$\boxed{Efficiency = 1 - \dfrac{T_c}{T_h}}$

here,

${T_c}$ = 400 k

${T_h}$ = 500 k

Hence,

Efficiency [η] = $1 - \dfrac{400}{500}$

→ $\dfrac{500 - 400}{500}$

→ $\dfrac{100}{500}$

→ $\dfrac{1}{5}$

→ $\dfrac{1}{5} \times 100$

→ 20 %

Therefore, Efficiency [η] is 20 %

• A Carnot Engine is a theoretical engine that operates on the Carnot cycle.

• It is an ideal reversible heat engine.

• Carnot Efficiency is the theoretical maximum efficiency one can obtain when heat engine is operated between 2 temperatures.

• Developed by Nicolas Leonard Sadi Carnot in 1824.

• Efficiency depends on the temperature of the hot and cold reservoirs.
