A student blew air into a balloon. The balloon got larger and larger.
Explain why the student cannot see the particles that make up the air in the balloon.
Explain how the particles of matter in air are related to the changing size of the balloon.
Enter your answer in the space here.
The student cannot see the particles that make up the air in the balloon because the particles are too small to be seen by the naked eye. They are also evenly distributed throughout the balloon, creating a homogeneous mixture that appears as a uniform mass to the human eye.
The particles of matter in air are related to the changing size of the balloon because they are responsible for creating the pressure inside the balloon that forces it to expand. When the student blew air into the balloon, they added more particles to the closed environment, increasing the number of collisions between particles and the walls of the balloon. This created a greater pressure inside the balloon, which caused it to expand until the pressure inside and outside the balloon reached equilibrium.
