If 42.15 grams of ice at 0 deg * C was placed in 450 grams of water at 24.2 deg * C and after a given amount of time when all the ice has melted the final temperature is 15.7C calculate the Molar Heat of Fusion for water based on the experimental values.
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
As per the law of conservation of energy, the heat lost by water is equal to the heat gained by Ice.
Ice uses the gained heat for the following two processes.
(i) Phase change of Ice from solid to liquid (water)
(ii) Raise of temperature of the water produced in (i) from 0oC to the final temperature i:e 15.7oC.
