Photosynthesis is the process by which green plants use sunlight, carbon dioxide, and water to produce glucose and oxygen. Glucose serves as food for the plant. To test for the presence of starch (formed from glucose), we use the iodine test—leaves turn blue-black, indicating successful photosynthesis.

Exothermic reactions release energy, usually as heat or light, making their surroundings warmer. Combustion and respiration are examples. Endothermic reactions absorb energy from the surroundings, causing a temperature drop. Photosynthesis and melting ice are examples. These reactions differ in energy flow but are essential in chemical and biological processes.

Sublimation is when a solid changes directly into a gas without becoming liquid. For example, camphor, a white crystalline solid, turns into v***r when heated. This is why camphor disappears when burned, leaving no liquid behind. Sublimation is also used in making dry ice and freeze-dried foods!

Water exhibits anomalous behavior due to its unique molecular structure. It expands upon freezing, making ice less dense than liquid water, and has a high boiling and melting point relative to its molecular weight. Its density peaks at 4°C. These properties arise from hydrogen bonding, crucial for Earth’s climate and life.

The role of parents in a child’s 10th board preparation is vital. They provide emotional support, create a distraction-free environment, encourage effective time management, and ensure a balanced routine with proper nutrition and rest. Motivating the child while avoiding undue pressure helps build confidence and reduces stress for better performance.

Refraction is the bending of light as it passes from one medium to another, caused by a change in speed. This phenomenon is responsible for effects like the distortion of objects underwater. Total internal reflection occurs when light attempts to move from a denser to a less dense medium at an angle greater than the critical angle, causing it to reflect entirely back into the denser medium. This principle is used in optical fibers and prisms.
