Your question boils down to whether the evaporative cooling of the liquid is temperature-dependent. Kinetic energy is often paired with potential energy, as potential energy can be defined as the energy stored prior to motion taking place. The kinetic energy of the water molecules that just evaporated is not exceptionally high or low. If a highly exothermic reaction also produces gaseous products, the latter may expand so rapidly that the result is an explosion — a net conversion of chemical energy into kinetic energy (including sound). The energy in the battery is able to start a motion and by doing so transfering to kinetic energy, nut the chemical energy in the battery isn't 'stored' in movement. Kinetic energy is also the work that’s needed to move an object with mass from rest to a particular speed. Answers: 1 … The Kinetic Theory of Gases. The kinetic energy, K, depends on the speed of an object and is the ability of a moving object to do work on other objects when it collides with them. Kinetic energy is the energy associated with objects in motion. Kinetic Energy: The molecules of a gas possess kinetic energy. There are many different kinds of energy, kinetic energy, chemical energy, heat energy, and electromagnetic energy, but fundamentally all energy is the same. Chapter 25. potential energy: ... kinetic energy: The energy possessed by an object because of its motion, equal to one half the mass of the body times the square of its velocity. What happens as a result? 3) why are the types of organisms that live at each underwater … But the total energy of the system, including kinetic energy, fuel chemical energy, heat, etc., is conserved over time, regardless of the choice of reference … The kind of motion may be translation, rotation about an axis, vibration, or any combination of motions.
