Saving Planet Earth small – is valuable, if we wish to ensure a future that is healthy for all life on planet Earth so we have to save earth from various types of Pollution, Waste food, Drained Water etc. The earth is our mother planet in which we born and understand learn to speak, learn to walk and learned everything that we are now able to do. "It is only planet in our solar system on which life exists which incredible biodiversity. People all over the world celebrate this grand event all to protect flora and fauna and clean up the earth on
Phase (matter) decrease in temperature. The energy required to induce the phase transition is taken from the internal thermal energy of the water, which cools the liquid to a lower temperature; hence evaporation is useful for cooling. See Enthalpy of vaporization. The reverse process, condensation, releases heat. The heat energy, or enthalpy, associated with a solid to liquid transition is the enthalpy of fusion and that associated with a solid to gas transition is the enthalpy of sublimation. While phases of matter are traditionally defined for systems in thermal equilibrium, work on quantum many-body localized (MBL) systems has provided a framework for
