GENCHEM

• Malleability - ability to be pounded into thin sheets.
• Ductility - the ability to be pulled into a wire.
• Solubility - the ability to dissolve in another substance.
• Thermal conductivity - ability to transfer thermal energy from one area to another
• Exothermic temperature - energy is released resulting to increase in temperature
• Endothermic - energy is absorbed, resulting to decrease in temperature.
• Extensive property - physical properties dependent on the size of the sample
• Intensive property - independent on sample size
• Intrinsic property - inherent properties dependent on the material type
• Extrinsic - outside appearance of substances
• COMPOUNDS - A substance made up of two or more elements chemically combined.
• Mole - the amount of substance that contains the same number of entities.
• Atomic mass - mass of a single atom
• Molecular mass - total mass of atoms in a molecule
• Molar mass - mass of 1 mole.
• Empirical formula - the simplest formula for a compound
• Molecular formula - the formula for a compound as it exists.
• Gas volume changes greatly with pressure.
• Gases have relatively low viscosity.
• Most gases have relatively low densities under normal conditions.
• Gases are miscible.
• Gases are highly compressible

  ➢ an increase in external force, compresses the gas sample, while decreasing the external force allows gas volume to increase.
