Situation: James has a balloon filled with air. He decided to squeeze the balloon gently. What change did James observe in the balloon?
Answer (2)
When James squeezes the balloon gently, he notices that its shape changes due to the increase in pressure in the squeezed area. The elastic material of the balloon allows it to deform and return to its original shape after the pressure is released. This observation demonstrates principles of physics, including gas behavior and elasticity.
;
When James squeezes the balloon gently, he is applying pressure to it.
Who and What : James, who is the person interacting with the balloon, observes a change in its shape when he squeezes it.
How and Why : When pressure is applied to the balloon, the air inside has less space to occupy, causing the balloon to compress and change shape. This is because balloons are flexible and the air inside them is compressible. The squeezing effect leads to a temporary deformation, which means the balloon will become flatter or more elongated depending on how it is squeezed.
Observation : So, the main change James observes is the alteration in the balloon's shape. As he applies more pressure, the volume of the balloon decreases, while when he releases the pressure, the balloon returns to its original size and shape.
This observation relates to the physics principles of pressure, volume, and the properties of gases (like air), which expand to fill the container they are in and compress under pressure.
