An ideal gas undergoes an adiabatic expansion, a process inwhich no heat flows into or out of the gas. As a result,(a) the temperature of the gas remains constant and thepressure decreases.(b) both the temperature and pressure of the gas decrease.(c) the temperature of the gas decreases and the pressureincreases.(d) both the temperature and volume of the gas increase.(e) both the temperature and pressure of the gas increase.

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.
