Give One Reason Why A Gas Completely Fills The Vessel In Which It Is Kept |
|
Answer» Gas have negligible force of attraction between them. So when they are released to a container they take all the space which is available for them. Gases have no fixed volume that\'s why it fills completely the vessel in which it is kept. ?????????? Because it is very free in nature and the space between the particles of gas is vey less so that it fills the vessel completely Gas fills completely The vessel in which it is kept because the due to high kinetic energy and negligible forces of attraction the particles of a gas are moving with a speed in all directions and the gas completely filled The vessel in which it is kept. |

Difference between immunisation and vaccination |
|
Answer» Immunization only incraese fighting capacity of your immune system against pathogen, it does not kill the pathogen but Vaccination kill the pathogen by blocking their biochemical pathways. \tDifference Between Vaccination And ImmunizationVaccinationImmunizationThe process involves Introducing a weakened / deactivated disease causing microbes into a personThe process starts after the person is exposed to the vaccine and the body starts building resistance to that diseaseIt is usually injected or administered orallyIt is not administered in any way, the body develops the resistance from vaccinesImovax Rabies is the trade name for rabies vaccineThe body builds up immunity through this vaccine for the disease rabiesVaccination does not guarantee complete resistance to a diseaseComplete immunity occurs when the person fully recovers from the diseaseUsually, if mutation happens to microbe, it might render the vaccine ineffective (this is the reason why common cold has no vaccine)Similarly, variations of a disease impact the body’s ability to generate an immune response\t |

Write archemedes principle |
| Answer» Archimedes’ PrincipleArchimedes’ Principle states that when an object is immersed fully or partially in a liquid, it experiences an upward force which is equal to the weight of liquid displaced by the object.Application of Archimedes’ PrincipleWhen the weight of displaced liquid by an object is greater than the weight of object, the object will float in liquid and when the weight of liquid will be smaller than that of the weight of the object, the object will sink in liquid.In submarines:\xa0In submarines, there is a tank which can be filled or emptied as per requirement. It is called buoyancy tank.When submarines have to go inside the water, the buoyancy tank is filled with water, so that, the weight of the submarines would become more than the weight of water displaced by it. And when submarines have to come over the surface of water, the buoyancy tank is emptied and water is replaced by air. In this condition, the weight of water displaced by submarines will become more than the weight of submarines and submarine comes over the surface of water. | |

Derivation of potential energy |
|
Answer» We know that w=f*s Work is equal to potential energyAccording to newton\'s second law of motion,f=m*a So in w=f*sP.E. = m*a*s We know that a=g So, P.E. = m*g*ss=h (distance covered) This concludes thatP.E. = m*g*h W=force ×displacement mg×h W=mgh PE=mgh |

What is thecooling cause of evoporation |
|
Answer» During evaporation process the particles of liquid gain energy from their surroundings in order to overcome the force of attraction between them. This causes loss of heat energy in the surroundings that is why evaporation cause cooling During evaporation process the particles of liquid gain energy from their surroundings in order to overcome the force of attraction between them. This causes loss of heat energy in the surroundings that is why evaporation causes cooling. |
