Required information Multi-step: Intermolecular forces and boiling points Read the overview and complete the interactivities that follow. Unlike gases, the behavior of liquids and solids cannot be described by a set of laws that can be applied regardless of the identity of the substance. Since liquids and solids are composed of particles that are much closer together, a force of attraction exists between them. The strength of these attractive forces will determine a compound's physical properties and its state of matter at a given temperature Arrange the molecule in the order of increasing boiling point. t +1 H Reset Increasing boiling point

Select the keyword or phrase that will best complete each sentence. Key terms: There are two types of energy energy is stored energy and energy is the energy of motion kinetic A compound with potential energy is more stable than a .compound with higher potential energy transition state energy of activation and AH is in When energy is released the reaction is said to be Since energy is released, the products are energy than the reactants exothermic enthalpy change The unstable energy maximum located at the top of the energy hill in an energy diagram is the E potential The difference in energy between the reactants and the transition state is the which is symbolized by negative lower The magnitude of the the reaction occurs determines the reaction rate - how fast higher Reset
