Question

An ideal gas heat engine operates in a carnot cycle between 227∘C and 127∘C. It absorbs 6 kcal at the higher temperature. The amount of heat (in kcal) converted into work is equal to -

Answer 1

Answer:

Yes

Explanation:

So,

Taking ∅ =25°

We can assume ΔKE to be equal to work

Now Fsin∅ ∝ U

However πC° is equal to U

⇒F ∝ U ∝ C

Taking constant proportionality are K

You get he rest ya?

Answer 2

An ideal gas heat engine operates in a Carnot cycle between 227∘C and 127∘C. It absorbs 6 Kcal at the higher temperature. The amount of heat (in Kcal) converted into work is equal to 1.2 Kcal.

• The heat engine works between the temperatures 227∘C (500K) and 127∘C (400K).
• So, Efficiency of the engine = 1 - (400/500) =0.2
• Now, we know, efficiency = Work done / Heat absorbed
• So, work done (W) = Heat absorbed * efficiency = 6 * 0.2 =1.2 Kcal.
