The large container has more water than the small container so it must have more thermal energy than the small container

A beaker of water left out on a counter at room temperature will equalize with the temperature of the room and once that happens, zero energy is required to maintain its temperature.
If you want to keep it cold, what you have to do is keep energy from the warmer environment outside from getting into the water you want kept cold.
If you are talking about keeping it hot, what you need to do is measure the amount of energy it is releasing to the environment and simply replace that amount of heat.
Now for the real physics answer.
If you imagine the beaker of water as a closed system and you are keeping track of any energy going into or out of it, all you have to do is keep the system balanced.
If you see 10 Joules of energy leaking out, you need to put that much energy back in to keep the temperature from falling.
If you see 10 Joules of energy sneaking into the water, you had better find a way to get it out of there or the temperature will rise.
If you see that there is no energy going into or out of your water, then its temperature is not changing and nothing is required to maintain the temperature.

How much energy is needed to keep one gallon of water from freezing?
None. When water freezes it _releases_ energy (the heat of fusion, 333.55 kj.kg). To keep it from freezing, simply keep the energy constant. If the ambient temperature is below zero C (32 F) the rate of energy loss will depend on the temperature of the air and the thermal resistance (insulation value) of the water's container, and other factors such as wind speed. In those conditions you must replace the energy lost to prevent the water from freezing. However, the energy needed depends on the rate of loss, not on the amount of water.
What temperature should bullfrog eggs be kept at?
They can be keep at a normal room temperature in water.
How do giant squid regulate their temperature?
The giant squid must keep its body temperature regulated because it will suffocate in warm water. To keep itself cool, it remains in cooler water and migrates as necessary.
When hotter atoms c they transfer their energy to colder atoms?
Yes, hot atoms must transfer their energy to colder atoms to keep the atomic temperature and movement balanced, and to keep these atoms alive.
What is the best way to distribute heat in water?
kinetic energy turns into heat energy which heat's the water SLOWLY (keep frantically moving) ;D

Why is energy needed by the body?
Energy is needed to keep your body in action!
What is importance of food for human beings?
It supplies us with calories. Calories are needed to keep the body temperature right and gives us energy to do things.
Do clouds influence temperature?
Yes, clouds and water vapor are major greenhouse gases. They trap energy entering and infrared energy leaving earth, helping heat the earth and keep it at a temperature suitable for life.
Where does the energy come from to keep the water cycle going?
the energy used in the water cycle is heat from the sun. it is the only source of energy needed in the water cycle.this is because it evaporates the water that forms clouds until the cloud cannot hold it any longer and bursts into rain.
What are examples of controlled variables in seed germination?
moisture and temperature you can control how much water the seed receives by putting in a particular amount of water naturally plants receive water by rainfall, you can also control the temperature if this is a lab exercise you can keep the room temperature at any amount that is needed.
What is the temperature of ice that is just touching the sea water?
The temperature of ice, for it to remain stable as ice is under 0c, but if you put energy into the ice, that will melt it, preventing that energy being used to raise its temperature. The ice is said to 'change state' from a solid to a liquid, and when energy is used to do this (lets say its warm sea water and energy goes from warmer to colder objects), the temperature change of the material as a result of more energy being put into it would decease. The same applies when water reaches boiling point: as you heat cold water, it gets hotter and hotter, until eventually the energy you are using to heat the water suddenly starts going into changing the state of the water from liquid to steam. This will mean that some of the energy is no longer available to keep heating up the water.
When you are walking on a cold day what is some of the energy in your body being used for?
It is used to keep your body temperature at a constant temperature
Turn Down The Heat On Your Water Heater?
Many homeowners do not realize that they can adjust the heat settings on their home's water heater. Although you can set your water heater to heat water until it is very hot, it is a good idea to keep your water heater's settings turned down to a lower temperature. Heating your water to a very hot temperature wastes energy. Additionally, if the water in your shower or sink is too hot, it could scald members of your household. Keep your water heater adjusted so that it does not cause burns or waste energy.
