Comparing the iceberg and the hot cup of coffee which one has more thermal energy Explain why?
The hot cup of coffee has more thermal energy than an iceberg. This is because thermal energy is directly related to temperature, and the cup of coffee is at a much higher temperature than the iceberg, meaning it contains more thermal energy.
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 are the example of thermal energy or internal energy?
Examples of thermal energy or internal energy include the heat energy released from a fireplace, the energy stored in the hot water of a geyser, and the kinetic energy of molecules in a cup of hot coffee.
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.
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).
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
Which two countries are the greatest coffee growers?
According to the search I've made, the Colombia is the greatest coffee grower...
What Starbucks coffee option has the least amount of caffeine?
The Starbucks coffee option with the least amount of caffeine is the decaffeinated coffee.
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.
