The rubber ball was squeezed by hands and deformed. Did the mass, weight, volume, density and pressure of the air in it change? If so, how?
The mass and weight of the ball do not change when it is compressed, since the ball remains sealed, and the air inside its cavity does not “go away” anywhere.
The volume of the ball decreases upon deformation from compression.
The density and pressure of the air in it increase, – its amount (mass) is now placed in a smaller volume, and the air pressure on the walls of the ball “from the inside” increases from compression (decrease in volume).
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
