Keisha finds instructions for a demonstration on gas laws. 1. Place a small marshmallow in a large plastic syringe. 2. Cap the s

yringe tightly. 3. Pull the plunger back to double the volume of gas in the syringe. Which best describes the purpose and outcome of the demonstration? This is a demonstration of Charles’s law. As the volume increases, the temperature decreases, and the marshmallow will freeze. This is a demonstration of Charles’s law. As the volume increases, the temperature increases, and the marshmallow will melt. This is a demonstration of Boyle’s law. As the volume increases, the pressure decreases, and the marshmallow will grow larger. This is a demonstration of Boyle’s law. As the volume increases, the pressure increases, and the marshmallow will shrink.

The accurate choice is option C. <span>This serves as an illustration of Boyle’s law. As the volume expands, the pressure diminishes, resulting in the marshmallow increasing in size.

Keisha is following the instructions for a demonstration of gas laws.
1. Insert a small marshmallow into a large plastic syringe.
2. Secure the syringe with a cap.
3. Pull back the plunger to double the gas volume in the syringe.

This activity occurs at a constant temperature, as there is no indication of any temperature change. Thus, as the plunger is drawn back, the volume doubles, leading to a reduction in pressure. Hence, </span>This is a demonstration of Boyle’s law. As the volume increases, the pressure decreases, and the marshmallow expands.
