Hydrosphere The movement of water around‚ over‚ and through the Earth is called the water cycle‚ a key process of the hydrosphere. In physical geography‚ the term hydrosphere (Greek hydro means "water") describes the collective mass of water found on‚ under‚ and over a planet’s surface. The Earth’s hydrosphere consists chiefly of the oceans‚ but technically includes clouds‚ inland seas‚ lakes‚ rivers‚ and underground waters. Hydrosphere refers to that portion of Earth that is composed of water. The

What are electrolytes? Chemically‚ electrolytes are substances that become ions in solution and acquire the capacity to conduct electricity. Electrolytes are present in the human body‚ and the balance of the electrolytes in our bodies is essential for normal function of our cells and our organs. Common electrolytes that are measured by doctors with blood testing include sodium‚ potassium‚ chloride‚ and bicarbonate. The functions and normal range values for these electrolytes are described below

Vibration- Rotation Spectroscopy of HCl and DCl Purpose: To determine the fundamental vibration frequency and bond length for H35Cl‚ H37Cl‚ D35Cl‚ and D37Cl and to compare the isotope effects to theoretically predicted values. Introduction Vibration spectroscopy is one of the most important tools for the accurate determination of molecular structure. Vibration spectroscopy also plays an important role in environmental chemistry. For example‚ the albedo of the earth’s atmosphere is controlled by the

An Introduction to Digital Logic Up until now the labs have dealt with electricity in its analog form where a quantity is described by the amount of voltage‚ or current‚ or charge... expressed as a real number. However a large proportion of electronic equipment‚ including computers‚ uses digital electronics where the quantities (usually voltage) are described by two states; on and off. These two states can also be represented by true and false‚ 1 and 0‚ and in most physical systems are represented
