Two pieces of identical metal are being heated at different rates. The first piece is receiving 20 J of energy per minute, and the second piece is receiving 40 J of energy per minute. Which is correct about the thermal energy? (1 point)
Responses
The thermal energy of the second piece is higher because it has a higher kinetic and potential energy.
The thermal energy of the second piece is higher because it has a higher kinetic and potential energy.
The thermal energy of the second piece is higher because it has a higher kinetic energy.
The thermal energy of the second piece is higher because it has a higher kinetic energy.
The thermal energy of the second piece is higher because it has a higher potential energy.
The thermal energy of the second piece is higher because it has a higher potential energy.
The thermal energy of the second piece is higher because it has a higher kinetic energy and lower potential energy.
The thermal energy of the second piece is higher because it is receiving more energy per minute.
The correct response is: The thermal energy of the second piece is higher because it has a higher kinetic energy.
To determine which piece has a higher thermal energy, we need to compare the amount of energy each piece is receiving per minute.
The first piece is receiving 20 J of energy per minute, while the second piece is receiving 40 J of energy per minute. Since the second piece is receiving double the amount of energy per minute, we can conclude that the thermal energy of the second piece is higher.
Therefore, the correct response is: The thermal energy of the second piece is higher because it is receiving a higher amount of energy per minute.
