Answer:Here's the explanation of what happens to the air inside the syringe and how it affects the marshmallow: Pressure and Volume Changes - Pushing the Plunger: When you push the plunger of a syringe, you decrease the volume of space available for the air inside. - Increased Pressure: As the volume decreases, the air molecules are squeezed closer together, leading to an increase in pressure. This is an example of Boyle's Law, which states that the pressure of a gas is inversely proportional to its volume (at a constant temperature). Marshmallow Transformation - Air Trapped Inside: Marshmallows are filled with tiny air pockets. When you push the plunger and increase the pressure inside the syringe, the air pressure outside the marshmallow becomes greater than the air pressure inside. - Marshmallow Compression: This pressure difference causes the air inside the marshmallow to be compressed, squeezing the marshmallow and making it smaller. - Face Distortion: The marshmallow's face, if it has one, will become distorted as the marshmallow is compressed. The features might become squished or flattened. In Summary: Pushing the plunger of a syringe increases the air pressure inside. This higher pressure forces the air inside the marshmallow to compress, resulting in a smaller, distorted marshmallow.
