Alesha, Kayden, Leo and Caroline are lab partners. They completed the lab in which they put a small marshmallow in a closed, see-through container. They then pushed a plunger down to decrease the volume of the container. They observed the marshmallow looking squished and crumpled. For their lab write up, they must identify the relationship between volume, temperature and pressure of a gas to explain what they saw during this experiment. Determine which student is correct from the statements below. A.
Alesha says the lab showed that when volume is decreased, pressure is increased. The increase in the pressure in the container is what made the marshmallow look squished and crumpled.

B.
Caroline says the lab showed that when volume is increased, pressure is increased. The increase in the pressure in the container is what made the marshmallow look squished and crumpled.

C.
Kayden says lab showed that when volume is decreased, temperature is increased. The increase in the temperature in the container is what made the marshmallow look squished and crumpled.

D.
Leo says the lab showed they increased the temperature of the container by breathing on it and decreased the volume by pushing down the plunger. Both of increasing the temperature and decreasing the volume caused the pressure to decrease and make the marshmallow look squished and crumpled.
