It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, structure, behaviour, and changes that occur when they interact with other things. The quantum mechanical approach is currently used...
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...

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...
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 ...

An exothermic reaction isa reaction in which energy is released in the form of light or heat. Thus in an exothermic reaction, energy is transferred into the surroundings rather than taking energy from the surroundings as in an endothermic reaction. In an exothermic reaction, change in enthalpy (...
Today, the idea that dinosaurs evolved into birds is back in the scientific forefront — but there's ongoing debate about their metabolism. Here's a run-down of some common arguments: The Case for Endothermic Dinosaurs Birds evolved from dinosaurs, so they must have inherited their warm-blooded...
