State of the System and State Functions - State of the system implies the conditions of its existence. In order to understand it, let H 2 O be considered as a chemical system. H 2 O can exist in three physical states; i..

. The total energy of the system is equal to the sum of the energies of the two H atoms. When the two atoms approach each other, electrons of one atom attract the nucleus of the other atom. Electrons of both the atoms are attracted by both the nuclei. These attractive interactio..

Tracheids are elongated dead cells that have sloping end walls. The cavity is empty as the cells are dead. The walls are thickened with a material called lignin. These thickenings are in different patterns. The cells are arranged end to end. Vessels are also dead cells that have variously patt..

Introduction - There are more than hundred elements around us. But, we do not find these elements in their native form. This is because most of these elements are highly reactive. They interact with each other to form simple or complex substances. Only elements with the noble gas configuration have..
