The vapor pressure of liquid heptane, C7H16, is 100 mm Hg at 315 K. A sample of C7H16 is placed in a closed, evacuated 579 mL container at a temperature of 315 K. It is found that all of the C7H16 is in the vapor phase and that the pressure is 64.0 mm Hg. If the volume of the container is reduced to 366 mL at constant temperature, which of the following statements are correct? (Select all that apply.) The pressure in the container will be 101 mm Hg. Only heptane vapor will be present. No condensation will occur. Liquid heptane will be present. Some of the vapor initially present will condense.
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.
