You have two identical containers, each filled with 1 mol of an ideal gas at identical temperature - one is filled with Ne, the other is filled with H2 . Assume atomic mass of Ne > atomic mass of H2 a) You increase the temperature of both containers by the same value. Do you need the same / more / less energy to increase the temperature of the Ne compared to H2 ? Argue and explain. b) How does the average speed of gas atoms / gas molecules in both containers compare to each other? Do the gases have the same speed in both containers or does one gas move faster or slower than the other? Argue and explain.

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.
