higher temperature?
A. The particles that make up the gold bar are moving more quickly.
B. The particles that make up the aluminum bar have more potential
energy
C. The aluminum bar has fewer particles than the gold bar.
D. The particles that make up the gold bar are larger.

characterization of nanoparticles is a critical step in nanomaterial production as it provides information of dimension, morphology, surface charge, distribution and degree of surface functionalization.
