Why respiration exothermic? |
|
Answer» Exothermic reaction is a reaction in which heat is involved. In the respiration heat is involved. Respirqtion is a exothermic reaction because energy is released during this process. It is given by C6H12O6 +6O2 ------- 6co2 +6H2O +Energy....? The food we eat get digested and combined with oxygen to release CO2 and H2o and heat also.so it is considered as exothermic process For the sustenance of life we require energy. We obtain this energy from our food. In the process of digestion, food molecules get converted into simpler substances such as, glucose. Then glucose combine with oxygen and provide energy to our body. The whole process is known as respiration. As because, energy is released during the process of respiration, so it is considered an exothermic reaction.For example:-C6H12O6 + 6O2 → 6CO2 + 6H2O + Energy |

Why the bar magnet have only two poles north and south? |
|
Answer» Bar magnet always points in north-south direction when left freely suspended because earth itself behaves like a magnet and north-pole of bar magnet is attracted towards south-pole of earth\'s magnet and vice versa. the northern direction. Taking these two ideas together, then, the Earth\'s magnetic field will cause the magnet to align north to south. That\'s why people na See what happens is that in a magnet there are only two sides if you take any magnet it will have two sides and reason why it is named as north and south is that when you place a compass over a magnet on both side the red one will show north amd blue one south on compass. Because it had two ends . The opposite poles of two magnets attract. Therefore, when the red end of a magnet or compass is pointing north, it is because it is being attracted in that direction by the south end of another magnet (often coloured blue) – this is the imaginary magnet inside the Earth. because it had only two ends whether horse shoe magnet has also only two poles north and south |

The definition of diffusion is different in terms of bio and chemistry chemistry |
| Answer» Bio =Diffusion is a physical process that refers to the net movement of molecules from a region of high concentration to one of lower concentration. The material that diffuses could be a solid, liquid or gas. Similarly, the medium in which diffusion occurs could also be in one of the three physical states.Chem=Diffusion is the process of a substance spreading out to evenly fill its container or environment. In a solution, a concentrated solute diffuses to spread evenly in its solvent. This is the process where the particles move from high concentration to low concentration. Diffusion explains why an open bottle of ammonia will fill an entire room with odor. The gas molecules escaping from the bottle spread out to fill their new container: the room. As a result, the whole room smells. Upon opening the windows, the gas will diffuse into the environment. | |
