Matrices and Determinants
Summary - A matrix is defined as a rectangular array of elements. If the arrangement has m rows and n columns, then the matrix is of order mxn (read as m by n). A matrix is enclosed by a pair of parameters such as ( ) or [ ]. It is denoted by a capital letter. Two matrices are said to be ..
The Open Hearth Process
The Open Hearth Process - A mixture of cast iron, scrap iron, iron ore (haematite) and lime is melted in an Open Hearth Furnace. The hearth is lined with silica (SiO 2 ) or calcined dolomite (CaO.MgO) based on whether the impurities present in cast iron. If the impurities are ma..

In an open pipe, when a compressed wave reaches the far end, the air at that point is, for an instant, at a pressure greater than the atmospheric pressure. Being an open end, the air there can vibrate with maximum freedom and so, it suddenly expands into the surrounding air. Thu..

In conjoint bundle xylem and phloem occur in the same bundle along the same radius. The conjoint bundle is of two types: Collateral where, the vascular bundle consists of only one set of xylem and one set of phloem. The collateral bundle can be either open or closed...
To Prove that Oxygen is Evolved during Photosynthesis
Take a few healthy twigs of Hydrilla, a water plant. Place it in a funnel and invert the funnel in a beaker of water. Invert a test-tube over the stem of the funnel. Leave the set-up in sunlight. After sometime, bubbles can be seen rising in the test-tube. Remove..
