11. At the end of a cooking cycle, a pressure cooker contains a mixture of water, steam, and food at a temperature of 120°C and 1.5 atm of pressure. The pressure is valve is opened and the pressure decreases, which alters water's boiling point and causes the contents of the pressure cooker to cool rapidly. Which statement best explains why the contents cooled rapidly after the pressure was released? A. Water lost heat as it vaporized. B. Water absorbed heat as it vaporized. Water lost heat as it condensed. C. D. Water absorbed heat as it condensed.

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.
