The melting point of a particular compound is fixed and it is an important identification of an unknown compound. The practice to determine the melting point of an unknown material In different ratio with a known material is important to get the exact melting point of the unknown material. In different ratio the melting point of the unknown material will be fixed as the melting point of a pure material doesn't depend on the ratio in which they are mixed with other material. To get the exact melting point it is always good to get the melting point twice in different ratio.
Most <span>scientists </span>suggest diminishing carbon dioxide outflows. Less carbon dioxide in the climate would be relied upon to diminish the quantity of biotic calculates biological systems. A biotic element is any living part that influences the number of inhabitants in another living being, or the earth.

Ice melting is a physical change because you are not getting rid of anything, it is simply transforming into another state. The ice is melting because it is heating up and causing the molecules to speed up ans spread out, meaning all of the ice`s properties are still there, just in a different form.
