Specified Topics

• Gases consist of particles moving randomly at high speeds
• Increasing temperature leads to increased average kinetic energy of gas particles
• Both temperature and mass of gas particles influence the average kinetic energy of gas particles
• As volume increases, pressure decreases due to increased collisions
• Increased temperature leads to increased collisions between gas particles and the container walls
• Hydrogen bonds are most likely to be observed in ethanol
• London dispersion forces occur between nonpolar molecules
• Iodine (I2) molecules experience London dispersion forces
• The strength of hydrogen bonding depends primarily on the electronegativity difference between atoms
• Boiling point is likely different between substances exhibiting and not exhibiting hydrogen bonding
• Polar functional groups increase solubility in water due to stronger interactions
• Substances with strong hydrogen bonding have a higher boiling point
• Liquids with significantly higher viscosity likely have stronger intermolecular forces, such as hydrogen bonding
• Unsaturated bonds _____ weaken intermolecular forces.
• Asymmetrical structures are more likely to exhibit dipole-dipole interactions
• Boiling point defines the temperature at which a liquid changes into a gas
• Surface tension causes the curvature observed in water droplets on a surface
• Evaporation is the conversion of a liquid into its vapor phase at the surface
• Vapor pressure is exerted by a vapor in equilibrium with its liquid phase
• Vapor pressure increases with increasing temperature
• Water is likely to have higher surface tension
• Liquids typically evaporate more rapidly at higher temperatures
• The rate of evaporation depends on temperature and surface tension
• Liquids with lower boiling points at the same pressure have higher vapor pressures
• Substances with higher surface tension likely have stronger intermolecular forces
