Question

22.A crystalline solid with really tightly bound atoms in its crystal lattice will tend to have ________ latent heat of fusion.

A. smaller

B. righthanded

C. negative

D. larger

23. The distribution of speeds in a gas has this property:

A. there are more higher speed molecules than any other kind.

B. slower molecules are distributed evenly everywhere.

C. the most populated speed is a medium speed in the middle of the distribution

Answer 1

For Creystalline solid, with really tightly bound atoms, we need higher energy to break the bond so they will have larger latent host of fusion optim is correct distributim fenetim, I we have maxwell's velocity the fraction of molecules having speed vand vedu flos - Chry) 4ave - mo2 4лу-е КТ.
