Liquid water has a specific heat capacity of 4.184 J/g∘C and an enthalpy of vaporization of 43.9 kJ/mol. Assume the enthalpy of vaporization does not change with temperature. When 4,000 J of heat are transferred to 1 mol of liquid water at 65 ∘C, what happens? The liquid water warms to the boiling point and all of the sample evaporates. The liquid water warms but does not reach the boiling point. The liquid water warms to the boiling point but none of the sample evaporates. The liquid water warms to the boiling point and a small amount of the sample evaporates.
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.
