Definitely the iceberg because it is much more massive compared to the others. Keep in mind internal energy is more than just heat. One exception would be if the iceberg was at absolute zero, but i doubt that is the case.

Why does an iceberg have more thermal energy than hot water?
why is because think about it a pot of water has a little bit of water so that means little bit of molecules. and an iceberg has to many. so even though an ice berg is cold doesn't mean its not heated so there are more moving molecules moving les fast then a small pot of water moving more fast and you should mesure it in kelvin aka 0* as lowest.
What is the difference between heat and temperture?
Heat is the AMOUNT of energy, Temperature is the CONCENTRATION of heat energy. For example; An iceberg (a big one) will have more heat energy than a cup of coffee (fresh and hot).
How does a cover on a coffee cup prevent heat escaping?
Covering up a coffee cup lowers the rate at which energy can escape from the cup. It does this through a combination of a few things, the most important is lowering the amount of heat removed through convection. Convection is the mode of heat transfer involved with flowing gases and fluids. The amount of heat it can remove (i.e. how fast it cools the coffee) is very much dependent on the temperature difference between the flowing gases and in our case, the coffee. The higher the temperature difference, the faster they would cool (makes sense, right). When you put a lid on the coffee, you have trapped the heated air inside the coffee mug. As a result, the temperature of the air rises until the temperature of the air and the temperature of the coffee are practically the same. Using our above reasoning, we know that the coffee cannot cool down from the air anymore since they are both at the same temperature. However, if you leave the mug uncovered, you allow fresh, cool room temperature air back into the mug. This means that the temperature difference between the flowing air and the coffee causes the coffee to cool down. Another reason hot coffee will cool down is because the heat of vaporization of the liquid coffee. The heat of vaporization is the amount of energy required to make a liquid phase change to a gas. This removes energy from the coffee, making it cooler. When you leave the coffee uncovered, the coffee vapor is allowed to escape to the environment. Liquids will continually evaporate gases until it reaches a equilibrium point (noted by the substances "vapor pressure"). It would take alot of coffee to fill up a whole room with coffee gases, so that it would stop evaporating. However, putting a lid on the coffee traps the evaporation and the coffee will stop evaporating MUCH sooner (remember, less evaporation means stays hotter longer). Hope this helps.
How would you describe coffee?
Coffee can be described as a beverage that consists of an infusion of ground coffee beans. Coffee can also be described as a seed of the coffee tree that is ground to make coffee.
Why does a cup of black coffee cool faster than a cup of coffee with cream?
Heat can easily penetrate single items. When cream is added to coffee then there is more matter to penetrate before the coffee is cooled.
Which countries produce the greatest amount of tea coffee and sugar?
China produces the greatest amount of tea coffee and sugar in the world
When a sealed Thermos bottle full of hot coffee is shaken what are the changes if any in a the temperature of the coffee b the internal energy of the coffee?
There is a large increase in the temperature of the coffee due to the large amount of kinetic energy inputed into the system through the shaking motion. Thus due to the heat being released there is a large decrease in the internal energy of the system
A person shakes a sealed insulated bottle containing hot coffee for a few minutes what is the change in the temperature of the coffee. what is the change in the internal energy of the coffee?
There is a large increase in the temperature of the coffee due to the large amount of kinetic energy inputed into the system through the shaking motion. Thus due to the heat being released there is a large decrease in the internal energy of the system.

The more mass a material has the greater the temparture?
Where in the world did that idea come from ? Compare an iceberg the size of California and a cup of coffee.
What causes cream to mix with coffee?
the amount of it causes it to have a reaction to the coffee
Which has more heat energy the ice sculpture or a lighted match?
First note that "thermal energy" is a term that is long since obsolete. The correct term is "Internal Energy". "Thermal energy" was a term that was in use when people thought of energy as being some kind of fluid called "caloric" that was transferred between things at different temperatures. With that said: an iceberg has more internal energy when compared to a hot cup of coffee mainly due to the variance in size. Total internal energy is not necessarily determined by the presence of heat but the mass of the molecules present.
