Consider a glass of ice water at 0 °C. Moisture from the air is observed to condense on the outer sides of the glass. This condensation causes the ice in the glass to melt faster than if there were no condensation. For this problem use Lv = 2430 kJ/kg for the latent heat of vaporization of water at 37 °C as a better approximation than Lv for water at 100 °C. a) Determine the mass of ice mice, in grams, in the glass that would melt as a result of the condensation of 7.8 g of water from the air onto the sides of the glass.
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.
