Dealing with three different samples (iron, glass, and water) in a thermodynamic experiment at 10°C. Rank the samples from lowest to highest final temperature after 100 kJ of energy is added to each 1.25 kg sample. For same samples, based on amount of heat energy absorbed, select in an order from least to greatest, if each sample increases in temperature by 20°C.

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.
