The statement that explains why the bar of aluminum has a higher temperature is the particles that make up the aluminum bar are moving faster.
What is temperature?
Temperature measures the degree of hotness or coldness of an object. It also measures the average kinetic energy of particles.
The average kinetic energy of a particle increases with increase in temperature of the object, which in turn causes an increase in the rate of collision of the particles.
Thus, we can conclude that, the statement that explains why the bar of aluminum has a higher temperature is the particles that make up the aluminum bar are moving faster.
The complete question is below:
A. The particles that make up the aluminum bar are moving more
