(II) You buy an “airtight” bag of potato chips packaged atsea level, and take the chips on an airplane flight. Whenyou take the potato chips out of your “carry-on”bag, you noticeit has noticeably “puffed up.” Airplane cabins are typicallypressurized at 0.75 atm, and assuming the temperatureinside an airplane is about the same as inside a potato chipprocessing plant, by what percentage has the bag “puffedup” in comparison to when it was packaged?

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.
