Answer:
1000 mL of water
Explanation:
The thermal energy of a substance is the total amount of energy- potential and kinetic energy contained in it. It depends on the temperature, mass and phase of the substance.
Since, the both the containers contain liquid water at same temperature, greater mass would have greater thermal energy. Thus, container having 1000 mL of water would have greater thermal energy.
(mass =density x volume
because, density is same, mass ∝ volume
greater volume means more mass)
