Is deodorant a liquid or in gaseous form and why |
|
Answer» Deodorant is in gaseous form because when it comes out with full pressure that\'s why we feel it as in liquid form Deaudrant is both in liquid and gaseous form . First it is in gaseous form and gases are highly compressible therefore, while filling it into container it is compressed and therefore its converted into liquid. Deaudrant is both form gaseous and liquid...first it is in gaseous form but keeping low temperature and high pressure it may converts in liquid form... |

Discovery of electrons explain |
|
Answer» Cathode ray disharge tube experiment In 1897; J. J. Thomson, a British physicist, proposed that atom contains at least one negatively charged particle. Later this particle was named as electron. Thomson called those particles ‘corpuscles’. he charge on an electron is 1.6×10−19 C.This charge is found to be smallest negative charge carried by any particle.So it is taken as unit negative charge. |

How does a desert cooler work on hot dry day |
| Answer» On a hot day ,the temperature is high and the humidity is low .The rate of evaporation increases with increase in temperature and decrease in humidity .A desert cooler functions on the principle of evaporation .The water takes heat from the hot desert cooler and evaporates .The evaporation of water cools the pads and the circulating water .As a result ,the incoming air also gets cooled down . | |

What is latent heat and what is latent heat of fudion |
|
Answer» The amount of heat which is required to convert one unit mass of substance into solid or liquid is called latent heat.The amount of heat which is required to convert one unit mass of solid into liquid is called latent heat of fusion Latent heat: The heat energy which has to be supplied to change the state of a substance is called its latent heat. Latent heat does not raise (or increase) the temperature. But latent heat has always to be supplied to change the state of a substance .The word ‘latent’ means ‘hidden’. The latent heat which we supply is used up in overcoming the forces of attraction between the particles of substance during the change of state. Latent heat does not increase the kinetic energy of the particles of the substance, so the temperature of a substance does not rise during the change of state.Latent heat is of two types:(i) Latent heat of fusion(ii) Latent heat of vaporization.(i) Latent Heat of Fusion (solid to liquid change): The heat which is going into ice but not increasing its temperature, is the energy required to change the state of ice from solid to liquid (water). This is known as the latent heat of fusion of ice (or latent heat of melting of ice). The latent heat of fusion (or melting) of a solid is the quantity of heat in joules required to convert 1 kilogram of the solid (at its melting point) to liquid, without any change in temperature. The latent heat of fusion of ice is 3.34×105 joules per kilogram (or 3.34 ×105 j/kg). |
