Why ice is more cool than the water at 273k? |
|
Answer» As when ice converts into water, water gains the heat energy which is equal to the latent heat of fusion. So it is not so cooler than ice at 273K There is something called Latent Heat. Latent Heat is required for phase transition from solid to liquid and from liquid to gas.Latent Heat of fusion is the energy required to change the phase from solid to liquid at melting point. So, water at 273k has more energy as compared to ice at 273k ,since ice can easily absorb energy from surrounding in the from of latent heat to form water whereas water has no such privilege hence ice is more effective in cooling than water at same temperature.HOPE THIS HELPS FRIEND. |

Why is temperture remain constant during the state |
|
Answer» Becoz all the energy is absorbed in latent heat During the change of state, the temperature is remain constant because the provided heat is utilised for breaking the force of attraction between the particles of the substance. This happenes at the boiling point of the substance and the heat is used that\'s called the Latent heat. In short the heat is used in the change the state of matter but the temperature is remain constant |

Why ice flotes on water |
|
Answer» Because it has vacant space b/w them and has lesser density than water Ritika\'s answer is awesome... Because it has some cavities filled with air which makes its density lesser than water.So that\'s why ice floats on water. Ice Density is less than that of water Because it has cage like structure due to this water is not closely packed in ice but have vacant space between them due to this it has smaller density than water and floats on water Because it have some space between them and in which air fill that\'s why ice flows on water |

Why does adesert cooler cool better on a hot dry day |
|
Answer» Vishkarma\'s ans is awesome... The cooling in a desert room cooler is caused by the evaporation of water. a desert cooler cools better on a hot and dry day because the higher temperature on a hot day increase the rate of evaporation of water, and the dryness of air low humidity of air also increase the rate of evaporation of water. And due to increase rate of evaporation of water, a desert room cooler cools better on a hot and dry day And really sorry for my wrong answer Because water absorb the heat and starting evaporation we know that evaporation have cooling effect A desert cooler cools better on a hot dry day because there is very less humidity or water vapour present in atmosphere due to which the rate of evaporation is high and causes cooling effect..Remember~high is the humidity, less will be the rate of evaporationLess is humidity, more will be the rate of evaporation.. The earthen pot or matka has a large number of extremely small pores in its walls. Some of the water kept in the earthen pot continuously keeps seeping through these pores to the outside of the pot. This water evaporate change into vapour continously by taking the latent heat of vaporisation from the earthen pot and the remaining water. In this way, the earthen pot and remaining water lose hest and get cooled. |
