1.	What type of defect can arise when a solid is heated ? Physical property is affected by it and in what why ?
Answer» When a solid is heated , a vacancy is created in the crystal . On heating , some of the lattice sites are vacant and the density of the solid decreases as the number of ions per unit volume decreases.
