Which of these would BEST describe the difference between an experiment and field study? A) Experiments are much more important to science than field studies. B) In the field study, it is much harder to control variables than in an experiment. C) in the field study, it is easier to control the variables than in an experiment. D) Experiments are always done by professional scientist while field experiments can be done by anyone

B) In the field study, it is much harder to control variables than in an experiment

Explanation:

Field study and laboratory experiments are both employed by scientists in discovering answers to investigations. However, while field studies are conducted in a natural or real world scenario, experiments are carried out in the confines of a laboratory.

One major difference between an experiment and field study is that IT IS DIFFICULT TO CONTROL VARIABLES IN A FIELD STUDY THAN IN AN EXPERIMENT. Experimental Research usually occurs under strict controlled conditions where only one variable is being tested at a time and the other controlled. However, in a field study, it becomes difficult to have only one variable being tested as several variables come to play.

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.
