A student has an insulated tank with a divider that separates the two halves of the tank. She pours 100 L of water in each half and has a digital thermometer in each half. The right side's water temperature is at 100 °C and the left side's water temperature is at 15 °C. She
removes the divider and closes the top. After a minute, the right side's water temperature is 80 °C, and the left side's water temperature is
at 35 °C
Which statement explains what the student can gather from the data about the energy distribution of the system?
O A Since the net change of each side is zero, there was no change in energy distribution.
O B. Since the temperature of each side changed the energy distribution became less uniform.
O c. Since the amount of data is so small, there is no way to know how the energy distribution changed.
OD. Since the temperatures of each side moved toward each other, the energy distribution became more uniform.
