What else can I help you with?
Which do you think contains more internal energya teaspoon of boiling water or a pan full of water at 50c?
A pan full of water at 50°C contains more internal energy than a teaspoon of boiling water because internal energy is related to both temperature and mass. The pan has more water (greater mass) at a lower temperature compared to the boiling water, so it would have more total internal energy.
What has more internal energy 25 kg of water or 25 kg of gold at thermal equilibrium?
The 25 kg of gold has more internal energy than 25 kg of water at thermal equilibrium because gold has a higher specific heat capacity and a higher melting point than water. This means that it takes more energy to raise the temperature of gold compared to water, resulting in gold having more internal energy even at the same temperature.
Why does melting ice require much less energy than boiling the same mass of water?
Because Water's latent heat of fusion is much less than its latent heat of vaporization. In English: It takes less energy to change a gram of ice at 0°C into a gram of water at the same temperature than it takes to change a gram of water at 100°C into a gram of steam at the same temperature.
What has the greatest amount of internal energy 1 an iceberg 2 a pencil 3 a laptop 4 a cup of cold water 5 a cup of hot coffee?
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 iceberg has the greater amount of internal energy?
Icebergs have a greater amount of internal energy compared to ice cubes because icebergs are much larger in size and mass, thus containing more molecules that contribute to their internal energy. The larger volume of an iceberg also allows it to absorb more heat from its surroundings, increasing its internal energy.

What has more thermal energy one gram of water at 75 degrees or 100 grams of water at 75 degrees?
(75'C)x(1g) < (75'C)x(100g) .'. The second option has more thermal energy.
Why would a burn by 1 gram of steam do more damage than a burn caused by 1 gram of water at the same temperature?
It requires energy to change the state of water from liquid (water) to gas (steam), so even thought they are at the same temperature, the same amount (1 gram) of steam holds more energy than 1 gram of liquid water at the same temperature. If the steam came in contact with a person's skin, it would lose energy, some of it absorbed by the person (causing damage), and it will not reduce temperature until it is condensed, because all of the energy lost was due to the state change.
What nutrient provides the most energy per gram?
Fat. More calories =more heat=more energy.
What fuel produces more energy per gram burned- Ethanol or paraffin?
Paraffin produces more energy per gram burned compared to ethanol. This is because paraffin has a higher energy density due to its chemical composition, which allows it to release more energy when combusted. Ethanol, on the other hand, has a lower energy content per gram.
A gram of fatty acid can yield how many more times the energy as one gram of glucose?
2
For each gram of reactant fusion produces energy than fission?
For each gram of reactant fusion produces more energy than fission.
What contains most energy protein lipids or carbohydrates?
Fats (lipids) contain the most energy per gram compared to proteins and carbohydrates. While proteins and carbohydrates provide 4 calories per gram, fats provide 9 calories per gram. So, gram for gram, fats contain more than twice the energy of proteins and carbohydrates.
Does it it take more energy to heat the water to 100 degrees celsius or boil it?
If by "boil" you mean have it all evaporate, that takes MUCH more energy. For example, to increase the temperature of one gram of water from 20 to 100 degrees Celsius, you need 4.2 joules/gram/degree times 80 degrees = about 336 joules; then, to evaporate all the water, you need an additional 2257 joules.
Why does melting ice require much less energy than boiling the same mass of water?
Because Water's latent heat of fusion is much less than its latent heat of vaporization. In English: It takes less energy to change a gram of ice at 0°C into a gram of water at the same temperature than it takes to change a gram of water at 100°C into a gram of steam at the same temperature.
