    1:13:44 THIS IS Q2 = 9 J
    Q1 = 10 J
    Q1 = W + Q2
    Q1 = 1 + Q2
    Q2 = Q1 - 1 -------(i)
    Q2/Q1 = T2/T1 = 9/10
    Q1-1/Q1 = 9/10 ( using (i) )
    Q1 = 10 J
    As Q1 is the heat rejected to room And Q2 is the heat gone to engine

    1:03:25 ........if someone have doubt
    The efficiency of Carnot engine if T₁ and T₂ temperature are initial and final temperature .
    condition 1 :- when η ( efficiency of engine ) = 1/6
    then, 1/6 = 1 - T₂/T₁ ---------(1)
    condition 2 : when temperature of sink is reduced by 65K then, η(efficiency of engine ) = 1/3
    e.g, 1/3 = 1 - (T₂ - 65)/T₁ -----------(2)
    solve equations (1) and (2)
    2(1 - T₂/T₁) = 1 - (T₂ - 65)/T₁
    2 - 1 = 2T₂/T₁ - (T₂ - 65)/T₁ = (T₂ + 65)/T₁
    T₁ = T₂ + 65
    Put it in equation (1)
    1/6 = 1 - T₂/(T₂ + 65)
    1/6 = (65)/(T₂ + 65)
    T₂ + 65 = 390 ⇒ T₂ = 325K or 52°C
    Conclusion : its 65k and not 65°C

    Sir why we didn't take -ve sign with work in adibatic compression as well as in isothermal comprression???

    • @varunsudhir6502
      @varunsudhir6502 3 года назад +9

      Hi, in isothermal compression as the volume decreases, according to sign convention the work should be negative. As V final is lesser than V inital the log term would be lesser than 1 and hence negative. So theres no need to keep an extra negative sign. In adiabatic compression, the final temperature is greater than the initial temperature but as 1- gamma would come as negative, the whole term would be negative. So no need for negative sign again. Hope this helped. Thanks.
