Explain what is meant by homeostasis and its importance in the body. Explain what homeostasis is and why it is so important to the proper function of the human body. Define and describe what is meant by homeostasis in animals, and differentiate the approach to homeostasis that endothermic and ...
As air is cooled, which gas condenses first: N_2, He, or H_2O? Explain. A gas absorbs 188 J of heat and then performs 310 J of work. What is the change in internal energy of the gas? What are evaporation and condensation? Which of these processes is endothermic and which is exo...
Power cycleWhat kind of power conversion system is in place?To know overall capabilitiesSteam Rankine, Gas Brayton, Stirling, thermoelectric, endothermic chemical reaction Average coolant temperature at plant outputAverage coolant temperature at inlet to turbine (or other process)To know which end uses...
A refrigerant(the chemical that is used to keep things cold) is turned from a liquid into a gas in the evaporator. This is an endothermic reaction, meaning the refrigerant absorbs the heat around it, making the slush machine cold. ... The constant movement also helps to make sure the slu...
Why melting of ice is called an endothermic process and not an endothermic reaction? Water is a higher energy state, as the liquid can rotate and vibrate while solid ice can only vibrate. This means forice to turn into a higher energy state (water) it has to absorb energy, hence it is...

Hibernation helps to conserve energy and occurs when food is not available. Endothermic animals naturally reduce their metabolic rate to conserve energy, thereby lowering their body temperature. Hibernation can last for a few hours, weeks, or months. Furthermore, hibernation can be observed in animal...
