In his experiment, Needham heated chicken broth in a flask in order to kill any living organisms within the broth. He allowed the broth to cool and placed it in a sealed flask. ... it can also create some order as well. Start studying Spontaneous Processes and Entropy. Search. Spontaneous generation is an incorrect and obsolete hypothesis about the possibility of life forms being able to emerge from non-living things. The reverse of a spontaneous process is a nonspontaneous process: Energy must be added in order for one to occur. In order to decide whether a reaction is spontaneous, it is therefore important to consider the effect of changes in both enthalpy and entropy that occur during the reaction. Needham also placed unheated broth in another container. The ability to maximize entropy by sorting different sized objects creates a kind of attractive force, called depletion, or excluded volume force. Spontaneous recovery is a phenomenon of learning and memory that was first named and described by Ivan Pavlov in his studies of classical (Pavlovian) conditioning.In that context, it refers to the re-emergence of a previously extinguished conditioned response after a delay. Anika is a 19-year-old college student living in the dormitory. Spontaneous definition, coming or resulting from a natural impulse or tendency; without effort or premeditation; natural and unconstrained; unplanned: a spontaneous burst of applause. Explain the theory of spontaneous generation and why people once accepted it as an explanation for the existence of certain types of organisms. See more.

Explain how certain individuals (van Helmont, Redi, Needham, Spallanzani, and Pasteur) tried to prove or disprove spontaneous generation. Spontaneous generation is the idea that living organisms can spontaneously come from nonliving matter.
