When the first law of thermodynamics is applied to a system, the Qand Wstand for what? Select one: O A. the heat flow into the system and the work on the system. O B. the heat flow out of the system and work done on the system. O C. the heat flow into the system and the work done by the system O D. the heat flow out of the system and the work done by the system.

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.
