Document Summary
Deals with energy transfers to the system and surroundings. Kinetic energy (- energy due to translational motion. Potential energy (- energy due to position within a field. Internal energy (u) - all other energy possessed by a system. Two forms of energy transfers (surroundings, system) Heat (q) - energy flow as a result of a temperature difference (q > 0 when transfer is into the system) Work (w) - all energy transfer not driven by temperature difference (w > 0 when energy is transferred into the surroundings) (constant pressure) (constant temperature) Final energy system - initial energy system = net energy transfer. If system is not accelerating (moving at constant speed is ok) If system is not moving changing in a force field. If system is not exchanging heat with surroundings (perfectly insulated) W = 0 all must be true. 2. 00 l of water are heated from to at a constant rate over 10. 0 min.
