Liquid Properties Quiz

Properties of Liquids

• Surface tension is the measure of the elastic force in the surface of a liquid.
• Vapor pressure is the pressure exerted by the gas in equilibrium with a liquid in a closed container at a given temperature.
• Viscosity is a measure of the resistance of fluid to flow.
• Boiling point is the temperature at which the liquid converts into a gas.
• Capillary action is the tendency of a liquid to rise in narrow tubes or be drawn into small openings.
• Molar heat of vaporization is the energy required to vaporize 1 mole of a liquid at a given temperature.

Types of Solids

• Crystalline solids have a crystal lattice structure, with a combination of unit cells forming a network.
• Amorphous solids have a random orientation of particles.
• Crystalline solids have distinct melting points, are generally incompressible, and have a repeating geometric structure.
• Amorphous solids melt gradually over a range of temperature, can be compressed, and have a random arrangement of particles.

Properties of Crystalline Solids

• Crystal lattice is a combination of unit cells forming a network.
• Unit cell is the smallest repeating structure.
• Crystalline solids have distinct melting points because applying heat breaks the bonds at the same time.
• They are generally incompressible because of the repeating geometric structure.

Properties of Amorphous Solids

• Amorphous solids have a random orientation of particles.
• They melt gradually over a range of temperature because the bonds do not break at once.
• They can be appreciably compressed because of the random arrangement of particles.

Types of Crystals

• Ionic crystals are made of different-sized particles, have high melting points and boiling points, and are not good conductors of heat and electricity as solids.
• Molecular crystals are held by weak London dispersion forces, dipole-dipole forces or hydrogen bonds, have low melting points, and are poor conductors of heat and electricity.
• Covalent crystals are extremely strong and very hard to break, have high melting points, and are poor conductors of heat and electricity.
• Metallic crystals are good conductors of heat and electricity, vary in melting points and hardness, and are malleable and ductile.
