Question 6 of 15

7. mark review Critical temperatures for A, B, C and D gases are 25°C, 10°C, -80°C and 15°C respectively. Which gas will be liquefied more easily?

Question 7 of 15

8. mark review Which is not correct about the Schottky defects?

Both cations and anions are missing from their lattice sites without affecting the stoichiometry of the compound

The presence of holes causes the density of the crystal to decrease

Because of presence of holes the lattice energy decreases.

The defect increases the electrical conductivity of the solid due to migration of the ions into the holes.
