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.
The efficiency of the LED bulb is 20% while The efficiency of the Inc bulb is 1%.
The lightbulb efficiency can be defined as the quotient between the amount of usable light and the amount of electrical power output. For the efficiency of the CFL Bulb:
