For condensation to take place there should be noticeable difference between the temperature of the system and the atmosphere. Thus condensation is the reason for clinging of water particles to the side of the glass.
What is condensation?Condensation is a process in which the vapor state converts to liquid state. Condensation is the reverse process of evaporation. Condensation occur at dew point. Dew point is the temperature at which condensation starts.
When the hot air particles collides with the surface of the glass having ice water, then the hot particles that had so much energy or kinetic energy suddenly reduces its energy and converts to water due to the change in temperature and pressure .
Thus condensation is the reason for clinging of water particles to the side of the glass having ice water.

7. Some products or processes claim to be "chemical free" or say "no chemicals added." Based on your understanding of chemistry, what are the arguments for and against such statements?
Please i need help
The meaning behind the statement is that the products does not contains any synthetic and harmful chemicals such as colourants, preservatives etc.
What are synthetic chemicals?All natural products or materials contains certain kind of chemicals which are naturally made in them. Such chemicals are natural chemicals and does not harm the living or causes any unwanted reaction.
The chemicals which are made by humans for specific purposes are called synthetic chemicals. Which can be of toxic and hazardous. Almost all materials we use everyday such as toothpastes, shampoo, food items, dyes, medicines and the fertilizers and pesticides we use in agriculture are all chemicals.
These chemicals helps in some way but they can be harmful to life in other way. Some products claim that they are chemical free, may true or not they intending to clear that the product does not contain any synthetic chemical except the required natural chemicals.

Nuclear fusion reactions release more energy than fission reactions while also generating less waste. However, nuclear fusion reactors are not currently used to generate electricity.
What is the main reason for this?
Nuclear fusion reactions release high energy and required tremendous temperature of nuclear reactors is the main reason for not used to generate electricity.
What are nuclear reactions?Nuclear reactions are those reactions which are taking place in the nucleus of any unstable atom and produces energy.
As in the question it is given that nuclear fusion reactions releases more energy and less wastage, but this energy are releases in the tremendous amount which can be proved harmful for the environment and the humans. To carry out this reaction we have to maintain the very high temperature of nuclear reactors of about 6 times greater than sun's temperature, which is not possible manually.
Hence, high temperature of nuclear reactors and high amount of energy released is the main reason.
