Why the smell of hot sizzling food reaches you several meters away than |
|
Answer» This is due to the fact that the rate of diffusion of hot gases is much faster than the rate of diffusion of cold gases released by cold food. This can be explained on the basis of tge process of diffusion with increases with the rise in temperature. Vapour of hot food evaporates rapidly than cold food. That\'s why the smell of hot sizzling food reaches us several meters away while getting the smell of cold food we have to go close. Because of the diffusion of particles from high concentration to low concentration |

NCDs can refer to chronic diseases which last for long periods of time and progress slowly. Sometimes, NCDs result in rapid deaths such as seen in certain diseases such as autoimmune diseases, heart diseases, stroke, cancers, diabetes, chronic kidney disease, osteoporosis, Alzheimer\'s disease, cataracts, and others. While sometimes referred to as synonymous with "chronic diseases", NCDs are distinguished only by their non-infectious cause, not necessarily by their duration, though some chronic diseases of long duration may be caused by infections. Chronic diseases require chronic care management, as do all diseases that are slow to develop and of long duration. |
