A body floats in water with one-third of its volumeabove the surface of water. If it is placed in some oil,it floats with half of its volume above the oil surface.Then, specific gravity of the oil is |
|
Answer» Let the total volume of the body be V. Its density be ‘d’ and the density of water be q = 1000 kg/m3 Weight of the body in air, W = Vdg Volume of body inside water = V – V/3 = 2V/3 So, buoyant force is = (2V/3)qg Let the density of the oil be ‘p’ and the volume of body inside that liquid is = V – V/2 = V/2 Again the buoyant force is = (V/2)pg Since, in both case the body floats so, (2V/3)qg = (V/2)pg => p = 4q/3 Hence specific gravity = 4/3 |

20) Define the terms a] Bond angle b] Bond order cCo-valent radiusăŚ1 |
|
Answer» Abond angleis theanglebetween two bondsoriginating from the same atom in a covalent species. eg. 1: eg. 2: Geometrically, abond angleis an anglebetween two converging lines. Bond order is the number of chemical bonds between a pair of atoms. For example, in diatomic nitrogen N≡N the bond order is 3, in acetylene H−C≡C−H the bond order between the two carbon atoms is also 3, and the C−H bond order is 1. Bond order gives an indication of the stability of a bond. The covalent radius, rcov, is a measure of the size of an atom that forms part of one covalent bond. It is usually measured either in picometres or angstroms, with 1 Å = 100 pm. In principle, the sum of the two co equal the covalent bond length between two atoms, R = r + r. |
