Answer: In the first Experiment, when the student opens the bottle and the gas escaped, it may escape with some portion of the soft drink, as it is under pressure, then the bubble will shrink and some may vanish. This is because the gas under pressure has escaped from the drink, thereby reducing the pressure in the drink.
For the second Experiment, when the student squeeze the bottle, he will increase the pressure of the gas in the soft drink, which makes the bubbles to grow and some will appear. This is because the squeezing of the bottle has tend to increase the motion of the gas in the bottle, which made the pressure to increase, and more bubbles to appear.
Explanation: bubbles in a drink is as a result of increase in the pressure of the gas in the drink. This gas will rise to the top of the bottle, as their want to escape from the bottle, their will rise with some portion of the drink, which we see as bubbles in the drink.

Straighterline the lowest or most basic needs in maslow's classification system are called <u>"biological"</u> needs.
Maslow's hierarchy of needs is a motivational theory in psychology containing a five-level model of human needs, frequently delineated as progressive levels inside a pyramid.
"Biological/Physiological" needs are the physical prerequisites for human survival. In the event that these necessities are not met, the human body can't work and will eventually fall flat. Physiological necessities are believed to be the most imperative and they are needs that ought to be met first.
