three students wrote explanations for why the room temperature copper pipe is cooled with liquid nitrogen before inserting them into a cuff with the same diameter. evaluate these explanations and indicate which one is the best because it includes the recommended statements for a good scientific explanation and is accurate.

student a: during the heat interaction, energy is transferred from the liquid nitrogen to the copper particles. consequently, the average kinetic energy and potential energy of the copper particles increase. increasing the potential energy of the copper particles means the
particles move further apart and the pipe expands, or gets larger in volume. when the pipe expands, its outer diameter is bigger and so it
now fits around the diameter of the cuff.

student b: a heat interaction occurs between the room temperature copper pipe and the cold liquid nitrogen. energy is transferred out
from the copper particles, and the average kinetic energy and potential energy of the copper particles decrease. decreasing the potential
energy of the copper particles means the particles move closer together and the pipe contracts, or gets smaller in volume. when the pipe contracts, its outer diameter is smaller and so it now fits inside the inner diameter of the cuff.

student c: during the interaction energy is transferred out from the copper particles, and the average kinetic energy and potential energy of the copper particles decrease. decreasing the potential energy of the copper particles means the particles move closer together
and the pipe contracts, or gets smaller in volume. when the pipe contracts, s outer diameter is smaller and so it now fits inside the inner
diameter of the cuff.
