Statement A : On heating, a solid usually changes to a liquid and the liquid on further heating changes to the gaseous state. Statement B : Arrangement of constituent particles is different in solid, liquid and gaseous state.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both Statements are correct.
4 Both Statements are incorrect.
Explanation:
On heating, the interparticle distance and freedom of movement of particles increase and interparticle forces decrease. Hence, on heating solids changes to liqids, where the particles are comparatively less close to each other and the particles are comparatively less close to each other and hence can move around. Liquids on further heating changes to gaseous state, in which the particles are far apart as compared to solids or liquids and their movement is easy and fast.
