Question

Emperature of 27°C. Which statement explains why the bar of aluminum has

a lower temperature?
O A: The particles that make up the aluminum bar are moving faster.
OB. The aluminum bar has more thermal energy.
OC. The gold bar has a higher density than that of the aluminum bar.
OD. The particles that make up the aluminum bar are moving more
slowly.

Answer 1

The aluminum bar has a lower temperature because its particles are moving more slowly.

Step-by-step explanation:

Temperature is a measure of the average kinetic energy of particles in a substance. In this case, the aluminum bar has a lower temperature because the particles that make up the bar are moving more slowly compared to those in the gold bar. The slower movement of particles results in lower kinetic energy and thus a lower temperature.
