Answer:
B
Step-by-step explanation:
The object with the most thermal energy is the choice B. This is because from the given choices, it has the most mass and highest temperature of all the bricks.
Thermal energy is the sum total of the average kinetic energy within the system.
It is mathematically expressed as:
Quantity of energy = mass x specific heat x change in temperature
We see that the quantity of the thermal energy is directly proportional to mass and temperature changes.
