As you leave a glass of water out, it warms. As it warms, various gasses (CO2, O2) become less soluble in it. Hence they escape from it in the form of these bubbles!
Carbonates drinks such as Pepsi contain Carbon Dioxide (hence the name). However, this gas will not stay mixed in with Pepsi unless under pressure (which explains why, when you open a bottle of Pepsi, you hear a fizzing). This is why, when you pour the drink into a glass, you see bubbles rising to the top and popping. These are bubbles of Carbon Dioxide escaping the mixture. When all the Carbon Dioxide has escaped the glass/bottle, the drink will go flat. In short, they escape into the atmosphere.
Take a steel glass and add chilled water in it and few ice cubes. And them simply keep it on a table. You will see after few seconds water is present on outer walls of glass. Thats because water vapour get condensed due to low tempreature.
I'm not sure what you mean by that, but if you need help with a crossword puzzle (homework?) then just see if there's anything that crosses over with the blank spaces if you know what I mean.
The bubbles you see are only excess air that has been deposited on the surfaces in the tank. They are perfectly normal and will dissappear in time.
Air bubbles in a water bottle can affect the overall quality and freshness of the water inside by potentially introducing contaminants or altering the taste of the water. The presence of air bubbles can also lead to a decrease in oxygen levels, which may impact the water's freshness and taste over time.
Surface tension.
Water vapour appears on the wall of the glass jar because the plant releases moisture through transpiration. When the jar is placed over the plant, the moisture released by the plant accumulates inside the jar and condenses on the cooler surface of the glass due to the temperature difference, forming water droplets or vapour.
To dissolve washing up liquid bubbles, you can simply add a small amount of vinegar to the water. The vinegar helps break down the soap molecules, allowing the bubbles to disperse more easily. Alternatively, you can wait for the bubbles to naturally break down over time.
Surface Tension
No, bubbles in soda water are carbon dioxide (introduced to the bottle when manufactured) whereas bubbles in regular water are entrapped air (introduced say by aerating over a water fall or the like - they can also occur in tap water by getting air in the pipes and then being entrapped when being pumped through the network of pipes to your house).
The water will eventually evaporate, leaving a dry, empty glass. Any Impurities or dust in the original water will remain as a slight staining on the glass. If the glass of water had stood in bright sunlight, algae may have formed, making any staining greenish in colour.
Non-polar gas molecules such as nitrogen and oxygen, which make up around 98% of the air, are not very soluble in water. There are two possible reasons why a standing glass of water will form bubbles if left over time. If you pour a glass of water you mix in additional gas to it which as the water / gas mixture returns to equilibrium, starts leaving solution (imagine oil sitting on water, stirring the two, and then watching the two separate again, the air above the water surface is like the oil in this case). Also as the temperature of water rises, the gas solubility falls and so they start to form bubbles out of solution. Water out of a tap may be cooler than the room. As the water warms up gas solubility falls, the equilibrium shifts, and gas and water start to separate.
