Question

Consider the process carried out for an ideal gas.

One by one, stoppers S1, S2, S3............ are removed slowly and the gas expands to V2, L with final pressure P2and final temperature T2. Which of the following is/are correct for the above process.

  1. T1=T2    
  2. P1=P2    
  3. U1=U2    
  4. w = 0, q =0    

The correct answer is: P1=P2


    It look as if process is reversible as it is carried out in small steps. But Pex = 0, so w = 0 The wall is diathermic, so process is isothermal. Hence, T1 = T2; So, capital deltaU = 0 ; So, U2 = U1 As gas has expanded without change in temperature, so pressure has decreased. capital deltaU = q + w ; So, q =

    Electronegativity is a feature which is relative and depends on several factor like oxidation number, hybridizations etc.
    For instance, the electronegativity of differently hybridized carbon are :
