In chemical energy, the chemical substance gets converted by undergoing various chemical reactions. Some amount of heat is released or gained during this, which is called an endothermic or exothermic process.Answer and Explanation: In the ionization process, the atom or molecule possess a negative ...
The yellow flames seen in a fire are the result of incomplete combustion, and the smoke produced (early stages of fire) is unburned carbon. As the fire gets hotter, more complete combustion occurs, less smoke is produced, and the flames lose the yellow color, turning more blue. The chemic...
B. The liquid loses enough energy to change to a gas. C. The Is the process of liquid water being converted to ice endothermic or exothermic? What happens to the kinetic energy of a molecule when a gas is heated? When a solid dissolves in water, heat may be...
athe exothermic heat generated during absorption to the generator. This provides the energy required for generation of the compressed vapor. [translate] a因为我看见你们说英语啊 Because I see you to speak English [translate] aolny time olny时间 [translate] aFig. 13. Effect of boiling temperature...
Why is freezing an exothermic process? Why does fog form dry ice? Why is evaporation a cooling process? Give a scientific reason. Why does a desert cooler cool better on a hot dry day? Briefly explain why it is important for the beaker of water to cool slowly...
Why do reactants become hotter during exothermic reactions when they are losing energy and why do reactants become colder when they are gaining energy in endothermic reactions? How do changes in interest rates by the central bank affect the economy? Which bronchus is slightly shorter? Why do ...
Is the phase change of gas to liquid endothermic or exothermic? Explain. A small cup of water is left out on the counter. Three days later, the water is gone. Which phase change describes what has occurred? (a) Melting (b) Sublimation (c) Evaporation (d) Condens...
Why is freezing an exothermic process? Why do dispersed colloid particles stay dispersed? Why do soft drinks have a pH of 3? Why/how is BHA used in consumer products? Why does saltwater freeze, but salt is used to melt ice? Why should the crucible and lid be heated gently at first?
How does the human body lose heat? How does human activity affect earth's renewable and nonrenewable resources? How does solar energy affect the hydrosphere? How do exothermic hand warmers work? How does the human body maintain a constant temperature? How does the solar cycle affect humans?Expl...
Decreasing the temperature usually increases the equilibrium constant of an exothermic reaction. Determine if the following statement is true or false. Heat of vaporization is the amount of energy it takes to change a solid to l...
