Match the following. Drag the appropriate labels to their respective targets Reset Help system loses thermal energy to the surrounding energy associated with the motion of an object energy associated with the temperature of an object energy associated with the position of an object energy associated with the relative positions of energy flows into the system from the surrounding potential energy thermal energy electrons and nuclei in atoms and molecules -AE +AE system gains thermal energy from the surroundings energy fiows out of system into the surroundings -W kinetic energy +w chemical energy -q work done by the system on the +q work done on the system by the

Answer 1

energy associated with the motion of an object energy associated with the temperature of an object energy associated with the position of an object kinetic energy thermal energy potential energy chemical energy energy assocated with the relative positions of electrons and nuclei in atoms and molecules energy flows out of system into the surroundings energy flows into the system from the surrounding +AE work done by the system on the surrounding -W work done on the system by the surrounding system loses thermal energy to the surrounding system gains thermal energy from the surroundings tw -9 +q

Kinetic energy is associated with motion of a body.

Potential energy is a function of position (mgh).

Chemical energy is due to attraction between electrons and nuclei.

Sign convention: Positive if work done on the system, heat/energy enters the system

Negative if work done by the system, heat/energy leaves the system.
