The normal density of a material is ρ and its bulk modulus of elasticity is K. The magnitude of increase in density of the material, when a pressure P is applied uniformly on all sides, will be:

Match List I with List II: List I A. Young's Modulus B. Compressibility C. Bulk Modulus D. Poisson's Ratio List II I. ΔdΔL × Ld II. FLA(ΔL) III. -1ΔP × ΔVV IV. -P × VΔV Choose the correct answer from the options given below:

Lack of toughness in a material directly implies high:
