Ethanol is nonpolar, it can dissolve in both polar and nonpolar substances.
The purpose of this experiment is to demonstrate the relationship between pressure and volume. Pulling the plunger back increases the volume of the gas in the syringe thereby increasing the size of the marshmallow but pressure is reduced. The relationship to be demonstrated is that pressure and volume have an inverse relationship.
You should re-upload this question with a picture of the plot below. Without access to that it’s impossible to answer this question.
Answer:
Accuracy is a term which describes how close to the real measurement our measurement is; while precision is a term that describes how close are a group of measurements one from another, or how close one from another are the measurements that an equipment does.
A precise measurement means that the equipment or measurement method gives always values so close to the previous value (similar values across the time), which means that for a specific measurement, the measurement results will be always so close between them; but of course, it does not guarantee that the results will be close to the real value in fact (The results can be precisive, be so close between them, but have every one an important error).

Explanation:
Nuclear fission is a nuclear reaction in which the nucleus of an atom splits into smaller parts (lighter nuclei). The fission process often produces free neutrons and releases a large amount of energy,for example, uranium, into smaller atoms such as iodine, caesium, strontium, xenon and barium, to name just a few. The fission of heavy elements is an exothermic reaction, and huge amounts of energy are released in the process.
If we look at the equation given in the answer, we will notice that a uranium-235 nucleus was bombarded with neutrons and it split into caesium-140, Rubidium-94 and more neutrons. This process takes place in nuclear reactors and is a self-sustaining process. It is self sustaining be cause more neutrons are produced, thereby continuing the fission reaction.
