Concept explainers

First law of Thermodynamics

The word thermodynamics consists of two words: thermo- and dynamics. Dynamics means the study of motion. The field of thermodynamics is all about the study of the movement of heat. In a more meaningful way, it is stated as the study of the transfer of energy. Energy transfer is something that we encounter in day-to-day life. Automobiles, chemical reactions, refrigerators, and power generators work on the basis of thermodynamic principles.

A 5.9 × 107 kg battle ship originally at rest fires a 1100-kg artillery shell horizontally with a velocity of 585 m/s. The firing of the shell results in a recoil velocity of -0.01091 m/s. Calculate the change of kinetic energy, in joules, for the ship and the shell. This energy is less than the energy released by the gun powder; in other words, there is significant heat transfer.
