    Increased kinetic energy, typically from heating, causes the molecules in a solid to vibrate more vigorously, weakening the intermolecular forces holding them in a fixed lattice structure. As these forces weaken, the molecules become less ordered, eventually overcoming the solid’s cohesive forces and transitioning into the more disordered liquid state, resulting in melting.

  2. When the temperature of a solid increases, the kinetic energy of its particles also increases. This added energy causes the particles to vibrate more rapidly within their fixed positions, leading to an overall increase in the internal energy of the solid.

  3. Diffusion describes the movement of particles from regions of higher concentration to regions of lower concentration. In a room, when a substance with a distinct odor is released, its molecules disperse through the air due to diffusion. Over time, these molecules spread evenly throughout the room, aRead more

    Diffusion describes the movement of particles from regions of higher concentration to regions of lower concentration. In a room, when a substance with a distinct odor is released, its molecules disperse through the air due to diffusion. Over time, these molecules spread evenly throughout the room, allowing the smell to be detected even in areas far from its source.

    Liquefied petroleum gas (LPG) cylinders offer portability, convenience, and efficiency for cooking purposes. They provide a reliable and controllable source of heat, allowing for precise cooking temperatures. Additionally, LPG is a clean-burning fuel, producing fewer emissions compared to traditional solid fuels like wood or charcoal, promoting better indoor air quality.

    The smell of food reaches our nostrils from the kitchen as aroma molecules released during cooking mix with air particles. These air particles, carrying the scent, diffuse outward from the kitchen into the surrounding environment. Eventually, they reach our nostrils, where specialized receptors detect and interpret the aroma, allowing us to perceive the smell of the food.
