Question | Answer |
---|---|
catalyst | substance that changers the rate of a chemical reaction without and change to its own structure |
conduction | transfer of energy by collision between atoms in a material |
convection | transfer of heat that occurs when particels move between objects of areas of deffrent tempreture |
enothermic reaction | chemical reaction that obsorbs energy |
energy | ability to cause change can change the speed, direction,shape,or temerature of an object |
exothermic reaction | chemical reaction that releases energy |
heat | transfer of energy from one object to another due to a difference in temperature flows from warmer objects to cooler objects |
kinetic energy | energy an object has due to its motion |
law of conservation of energy | states that energy cannot be created or destroyed but can only be tranformed from one from into another |
potential energy | energy that is stored due to position |
radiation | energy that is transfered by waves |
temperature | measure of the average kinetic energy of the atosm of an object |
