The air circulating in your laboratory is usually at 25.0°C and a relative humidity of 47.0%. You want to set up a cold room in the lab, but you do not want moisture condensing on the glassware in the cold room. At what temperature setting (in °C) would the humidity of the air just reach saturation and begin to condense on the glassware? Use 40.7 kJ/mol as the ∆Hvap of water.
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.
