Explanation: 1) Matter is composed of exceedingly small particles called atoms. An atom is the smallest unit of an element that can participate in a chemical change. 2) A macroscopic sample of an element contains an incredibly large number of atoms, all of which have identical chemical properties. 3) A compound consists of atoms of two or more elements combined in a small, whole-number ratio. In a given compound, the numbers of atoms of each of its elements are always present in the same ratio. 4) Atoms are neither created nor destroyed during a chemical change, but are instead rearranged to yield substances that are different from those present before the change

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
