Properties of Substance

Science > Chemistry > Introduction to Chemistry > Properties of Substance All matter has physical and chemical properties. Extensive properties are those properties of a substance which depend on the amount of substance. They vary with the amount of the substance. Examples: Mass, weight, and volume. Intensive properties are those properties of a substance which do not depend […]

1 Comment on Numerical Problems on Poisson’s Ratio

Science > Physics > Elasticity > Numerical Problems on Poisson’s Ratio In this article, we shall study the concept of poisson’s ratio and numerical problems on it. The concept of this constant (Poisson,s ratio) was introduced by physicist Simeon Poisson. When a rod or wire is subjected to tensile stress, its length increases in the […]
