How would you account for the effect of Schottky defect on the density of the ionic solid?

Due to Frenkel defect the density of ionic solid

How would you interpret the Q = W for a cyclic process ?

How would you explain the fact that the first ionization enthalpy of sodium is lower than that of magnesium but its second ionization enthalpy is higher than that of magnesium?

Explain with diagram, Frenkel defect. What are the conditions for its formation? What is its effect on density and electrical neutrality of the crystal?

A 1.000 mL sample of acetone, a common solvent used as a paint remover, was placed in a small bottle whose mass was known to be 38.0015 g. The following values were obtained when the acetone filled bottle was weighed : 38.7798 g, 38.7795 g and 38.7801 g. How would you characterise the precision and accuracy of these measurements if the actual mass of the acetone was 0.7791 g ?

Give scientific reasons: You know that as we go higher than the sea level, the boiling point of water decreases. What would be effect on the melting point of solid?

From the terrace of building of height H, you dropped a ball of mass m. It reached the ground with speed v. Is the relation mgH = frac(1)(2)mv^2 applicable exactly ? If not, how can you account for the difference ? Will the ball bounce to the same height from where it was dropped?

In the crystals of which of the following ionic compounds would you expect maximum distance between the centres of the cations and anion?

How would you demonstrate that yeast can respire both aerobically and anaerobically?
