In solids interatomic forces are
In solids, the interatomic forces are **both attractive and repulsive**. The atoms or molecules in a solid are held together by attractive forces such as covalent, ionic, or metallic bonds; however, as atoms approach closer, repulsive forces begin acting due to the electron cloud interactions.

Define ionisation energy. What is its value for a hydrogen atom?
Ionization energy is the energy required to remove the outermost electron from an atom in its ground state to infinity. For a hydrogen atom, its ionization energy is 13.6eV (electron volts) or 2.18 × 10⁻¹⁸ J. For more visit here: https://www.tiwariacademy.com/ncert-solutions/class-12/physics/chapterRead more

Breathing practices in Prānāyāma promote deep, rhythmic breathing, enhancing lung capacity and oxygen supply. These practices calm the nervous system, reduce anxiety, and improve mental clarity. Regular practice fosters mindfulness, concentration, and emotional balance. Additionally, they strengthen respiratory health, support overall physical well-being, and improve energy flow, contributing to harmony between body and mind. These benefits make Prānāyāma essential for holistic health.
See lessHow does Prānāyāma impact the major systems of the body? Name the systems it influences.
Prānāyāma positively influences the digestive, circulatory, respiratory, excretory, and nervous systems. By promoting better oxygenation, it ensures smooth functioning of these vital systems. It calms the nervous system, reduces anxiety, and improves concentration. The practice also aids digestion,Read more
Prānāyāma positively influences the digestive, circulatory, respiratory, excretory, and nervous systems. By promoting better oxygenation, it ensures smooth functioning of these vital systems. It calms the nervous system, reduces anxiety, and improves concentration. The practice also aids digestion, regulates blood circulation, enhances lung efficiency, and supports toxin elimination. Collectively, these effects contribute to overall physical, mental, and emotional well-being.
