Continue ReadingTemperature: The degree of hotness or coldness of a body is known as its temperature. Temperature of a system depends upon the kinetic energy of its molecules. Higher is the kinetic energy of molecules, higher is its temperature and vice versa. The measurement of temperature with the help of some instrument is known as thermometry and the […]

Raman while studying the scattering of light by liquids found that when a beam of monochromatic light was passed through organic liquids such as Benzene, toluene etc, then scattered radiation contained other frequencies in addition to that of incident light. The scattering of light from molecules with a […]
Continue ReadingPressure: Force experienced per unit area is known as pressure. Pressure = Force / Area Units of pressure is Newton / metre2 or N / m2 Example – Liquids and gases exert pressure on the walls of the container. Absolute pressure (pa): The pressure measured above absolute zero of pressure is called absolute zero pressure. A absolute zero pressure occurs only […]
Continue ReadingPhotosynthesis: It is a process in which the green chlorophyll-containing cells of the plants synthesize the carbohydrates from CO2 and water in the presence of sunlight. Equation for the photosynthesis can be written as: (Sunlight) 6CO2 + 12H2 O → C6 H12 O6 + 6H2 O + 6O2 (Chlorophyll) The products of photosynthesis make the structure of plants. Some […]
