A pronghorn antelope can run at a remarkable 18 m/s for up to 10 minutes, almost triple the speed that an elite human runner can maintain. For a 32 kg pronghorn, this requires an astonishing 3.4 kW of metabolic power, which leads to a significant increase in body temperature. If the pronghorn had no way to exhaust heat to the environment, by how much would its body temperature increase during this run? (In fact, it will lose some heat, so the rise won’t be this dramatic, but it will be quite noticeable, requiring adaptations that keep the pronghorn’s brain cooler than its body in suchcircumstances.)

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.
