  Thermit process is a metallurgical reaction where a mixture of aluminum powder and a metal oxide, typically iron oxide, undergoes an exothermic reaction, producing molten metal and heat.
  White light is passed through a prism to yield a spectrum. (a) The ray of which colour will show the maximum angle of deviation and which one will show the least angle of deviation? (b) A blue-coloured ray is passed through a glass prism. What will be the colour of the emergent ray? Justify your answer.
  When light passes through a prism, it undergoes refraction, separating into its component colors due to varying speeds in the different wavelengths. This dispersion reveals the spectrum, showcasing distinct hues.
  Liver disease encompasses various conditions affecting the liver’s structure or function, often caused by infections, alcohol misuse, fatty liver, or autoimmune disorders. Symptoms may include jaundice, fatigue, and abdominal pain.
  Control and coordination are essential physiological processes in living organisms. They ensure harmonized functioning of body systems through nervous and endocrine systems, maintaining homeostasis and enabling responses to stimuli.
  Resistivity is a material property measuring its inherent opposition to electric current flow. It is quantified in ohm-meters (Ω·m) and depends on a substance’s composition and temperature.
  A rainbow is a meteorological phenomenon characterized by a spectrum of colors appearing in the sky due to sunlight refracting, reflecting, and dispersing in water droplets, creating a beautiful, multicolored arc.
  Normal human vision involves light entering the eye, refracting through the cornea and lens, forming a focused image on the retina. Signals are sent to the brain via the optic nerve, enabling clear sight.
  Vision defects include myopia (nearsightedness), hyperopia (farsightedness), astigmatism, and presbyopia. These conditions result from abnormalities in the eye’s shape or lens flexibility, affecting the ability to focus clearly.
  Hormones are chemical messengers secreted by glands, regulating various physiological processes. Examples include insulin, estrogen, and adrenaline. They travel through the bloodstream, influencing growth, metabolism, and other bodily functions.
