8.   which of the following statements is accurate?           a. if an object's velocity decreases, then the object is accelerating.   b. if an object is said to be decelerating, its velocity must be increasing.   c. if an object's velocity remains constant, its acceleration must be increasing.   d. if an object's velocity is changing, it's either experiencing acceleration or deceleration.

When many atoms are split in a chain reaction, a large explosion occurs. this is an example of what type of energy conservation

When temperature of a substance increases, of its particles increase resulting in more between particles. real world applications of thermal expansion absolute zero (-273 degrees c) is the lowest possible temperature on the kelvin scale. it is a measure of where a substance has no kinetic energy. heat is a process of the . energy flows spontaneously from a object to a until equilibrium is reached. heat is measured in heat is transferred throughis a method of heat transfer that occurs between particles of matter that are in direct contact with each other. are poor conductors that impede / reduce the rate of heat transfer. is a method of heat transfer that occurs in fluids (non-solids) by means of currents. real world application of convectiona method of heat transfer through electromagnetic waves. when energy moves from one object to another inside a closed system, no energy is or in the system in the transaction. systems will spontaneously move to a state of organized energy or high disorder over time called

How to tell if two objects are in thermal equilibrium 1.the objects have the same temperature 2.the objects are the same size 3.the objects are touching each other 4.the objects temperatures are changing
