Energy Changes1. Energy is the ability to cause change.2. Energy can have different forms, Energycan be transformed from one form intoanother.3. Kinetic energy is the energy an object hasdue to its motion. Kinetic energy increasesas the speed of an object increases.4. Potential energy is stored energy thatincreases as an object’s height increases.Temperature1. Temperature is a measure of the averagekinetic energy of the particles in a material.2. The movement of energy from a warmerobject to a cooler one is called heat.3. Heat can be transferred by conduction,convection, and radiation.Chemical Energy1. The energy stored in chemical bondsis chemical energy.2. Chemical reactions can release or absorbenergy. Exothermic reactions are chemicalreactions that release energy. Endothermicreactions absorb energy.3. Changing the temperature and addingcatalysts can change the rate of chemicalreactions.Copy and complete the following concept map on energy.EnergyCompounds changewhen energy breaks orforms chemical bondsTransfer of energydue to differencein temperatureTemperatureThat absorbs heatTransferred whenparticles move from oneplace to anotherExothermicConductionred.msscience.com/interactive_tutorCHAPTER STUDY GUIDE 187
