What is the difference between fusion which is inter mixing of molecules of |
| Answer» The kinetic theory describes a gas as a large number of submicroscopic particles (atoms or molecules), all of which are in constant rapid motion that has randomness arising from their many collisions with each other and with the walls of the container.Diffusion refers to the process of particles moving from an area of high concentration to one of low concentration. The rate of this movement is a function of temperature, viscosity of the medium, and the size (mass) of the particles. Diffusion results in the gradual mixing of materials, and eventually, it forms a homogeneous mixture.Not only do gaseous particles move with high kinetic energy, but their small size enables them to move through small openings as well; this process is known as effusion. For effusion to occur, the hole’s diameter must be smaller than the molecules’\xa0mean free path\xa0(the average distance that a gas particle travels between successive collisions with other gas particles). The opening of the hole must be smaller than the mean free path because otherwise, the gas could move back and forth through the hole.Effusion is explained by the continuous random motion of particles; over time, this random motion guarantees that some particles will eventually pass through the hole. | |

How we can find that what is state of water or ice at 0°c,25k, 25°c ? |
|
Answer» (c) At 100ºC\t\xa0At 100°C, water exists in a Gaseous state.\tWe know that the boiling point of water is 100°C.\tThe water starts to evaporate after attaining this high temperature.\tExample: When you boil water at your home after some time you observe the vapours coming out of the vessel. These vapours are the gaseous state of water. 0ºC\t\xa0At 0°C, water exists in solid-state.\tWe know that the freezing point of water is 0 °C.\tThe liquid form of water starts to become solid (ice) at this temperature.\tExample: If you keep an ice cube tray filled with water and freeze it for a few hours, you may observe the cubes where you poured water has become solid. Ice is the solid-state of water.\xa0 25\xa0º C\t\xa0Water at 25°C is present in the liquid state.\tThe water which we use for our day to day activities is in the liquid state.\tThe water which we use for drinking, cooking, washing, etc all are in a liquid state. |

10 examples of newtons third law of motion |
| Answer» 1.A gun recoils when a bullet is fired from it: When a bullet is fired from a gun, the gun exerts a force on the bullet in the forward direction. This is the action force. The bullet also exerts an equal force on the gun in the backward direction. This is the reaction force. Due to the large mass of the gun it moves only a little distance backward by giving a jerk at the shoulder of the gunman. The backward movement of the gun is called the recoil of the gun.2.A man walking on the ground3.Rowing a boat\xa04.A person is moving forward during swimming5.Rocket propulsion6.\xa0A bird\xa0while flying pushes the air downwards with the help of its wings.7.\xa0When\xa0a person is lying on a bed, his weight is opposed by a reaction force from the bed (assuming it must be there because of Newton’s third law of Motion). | |

10 examples of newtons second law of motion |
| Answer» \tIf you use the same force to push a truck and a car, the car will have more acceleration than the truck because the car has less mass.\tIt is easier to push an empty shopping cart than a full one, because the full shopping cart has more mass than the empty one. This means that more force is required to push the shopping cart.\tWhen a person kicks a ball the person exerts force in a specific direction, that is the direction in which it will travel. In addition to this, the stronger the ball is kicked, the stronger the force we put on it and the further away it will travel.\tSuppose two people are walking and among the two people, if one is heavier than the other, then the one weighing heavier will walk slower because the acceleration of the person weighing lighter is greater.\tWhen riding a bicycle, the bicycle acts as mass and our leg muscles pushing on the pedals of the bicycle is the force. | |

10 Examples of newtons first law of motion |
| Answer» \xa01. Catching a cricket ball: When a fielder catches a cricket ball, he drags his hands backwards in order to increase the time taken by the ball to reduce its momentum to zero. This reduces the rate of change of momentum, thereby decreasing the force exerted on the hands by the ball.\xa02.\xa0Seat belts in a car: When brakes are suddenly applied or a car crashes with an object, the seat belts increase the time taken to move forward, thereby decreasing the rate of change of momentum. Thus, the force of impact is reduced and fatal accidents can be prevented.3. Athletes lands on sand: When an athlete lands from a height on a hard floor, he may hurt his feet because his feet comes to rest instantenously. So, a very large force is exerted by the floor on his feet. On the other hand, when he lands on sand, his feet pushes the sand for some distance, therefore the time duration in which his feet comes to rest increases. Thus, the force exerted on his feet decreases and he is saved from getting hurt. | |
