What is the BEST description of what will happen when the plunger is pulled out?
Responses
A The marshmallow will expand because the volume inside the syringe has increased.The marshmallow will expand because the volume inside the syringe has increased.
B As the pressure increased in the syringe the volume of the syringe and the marshmallow increased.As the pressure increased in the syringe the volume of the syringe and the marshmallow increased.
C The marshmallow expands because the volume has increased and the pressure inside the syringe has decreased.The marshmallow expands because the volume has increased and the pressure inside the syringe has decreased.
D There is a direct relationship between volume and pressure so as the volume increases the pressure increases. The marshmallow shrinks.
C The marshmallow expands because the volume has increased and the pressure inside the syringe has decreased.
C The marshmallow expands because the volume has increased and the pressure inside the syringe has decreased.
The BEST description of what will happen when the plunger is pulled out is option C: The marshmallow expands because the volume has increased and the pressure inside the syringe has decreased. To understand why, let's break down the explanation:
When the plunger is pulled out, it increases the volume inside the syringe. As the volume increases, the pressure inside the syringe decreases. This is because there is now more space for the air molecules to spread out, resulting in a lower pressure. As a result, the marshmallow inside the syringe expands. This is because the decrease in pressure allows the air trapped inside the marshmallow to expand and take up more space, causing the marshmallow to expand as well.
Understanding the relationship between volume and pressure is important in this scenario. The relationship is described by Boyle's Law, which states that there is an inverse relationship between the pressure and volume of a gas at constant temperature. As the volume increases, the pressure decreases, and vice versa.
So, in summary, when the plunger is pulled out, the increase in volume leads to a decrease in pressure, causing the marshmallow to expand.
