How much heat is absorbed for 1 kg of liquid gets vapourised into boiling point?
The amount of heat absorbed by 1 kg of liquid to vaporize it depends on what that liquid is, (water?), and what the temperature of the liquid is at the start of the process. Obviously, it will take more heat to vaporize 1 kg of liquid that is at 0º than it will to vaporize 1 kg of liquid that is at, say, 30º.
What is energy that is absorbed by the land and water is changed into?
Velium gas
How much heat energy is needed to vaporize g of water at its boiling point of K?
1oo calories for 1 g
When heating a sample of pure water to the boiling point why doesn't all of the water instantly vaporize when you reach the boiling point?
When water reaches its boiling point, it does not instantly vaporize because the heat energy is being used to break the hydrogen bonds holding the water molecules together. As the temperature continues to rise, more energy is transferred to the water molecules, causing them to break free and become vapor. This process of reaching a balance between the energy input and the energy needed to break the intermolecular forces takes time, so the water does not vaporize instantly.
What are some physical endothermic phenomenons?
Melting ice: When ice absorbs heat energy from its surroundings, it melts and its temperature rises. Evaporation of water: As water molecules break free from the liquid state to vaporize, they absorb heat energy from their surroundings. Photosynthesis in plants: Plants absorb sunlight to convert carbon dioxide and water into glucose, a process that requires energy and is endothermic.
How many joules of heat are needed to completely vaporize 24.40 grams of water at its boiling point?
The heat of vaporization of water is 40.79 kJ/mol. First, determine the number of moles in 24.40 grams of water. Then, convert moles to joules using the molar heat of vaporization. This will give you the amount of heat needed to vaporize 24.40 grams of water.
Energy that is absorbed by land and water is changed into?
Heat energy. This absorbed energy warms the land and water, leading to an increase in temperature.
Where is most of the sun's energy absorbed in water?
Most of the sun's energy is absorbed in the top few meters of water, where sunlight can penetrate. This energy is absorbed by water molecules and particles in the water, which then transfer heat to the surrounding water through conduction and convection.

When water is vapourisied energy is absorbed or released?
Energy is absorbed when water is vaporized. This is because the process of vaporization requires breaking the hydrogen bonds between water molecules, which requires energy input to overcome the intermolecular forces holding the liquid water together.
Which energy source produces steam?
Thermal energy, when absorbed by water
How much energy in kilocalories is absorbed when 9.0 mol of water is vaporized?
The enthalpy of vaporization of water is about 40.79 kJ/mol. Converting this to kilocalories, the energy absorbed when 9.0 mol of water is vaporized is approximately 9.72 kcal.
In order to get liquid water to become water to become water vapor what must be energy?
Energy must be added to liquid water so that it reaches the boiling point, at which point the water will vaporize into water vapor.
What happens to that energy from the sun that is absorbed by earth surface?
Energy from the sun that is absorbed by the Earth's surface is reflected back into the atmosphere or absorbed by land and water and transformed into heat.
What happens to the energy from the sun that is absorbed. by earths surface?
Energy from the sun that is absorbed by the Earth's surface is reflected back into the atmosphere or absorbed by land and water and transformed into heat.
How much of the suns energy is absorbed by land and oceans?
Roughly 70% of the sun's energy is absorbed by the Earth's surface, with about 51% absorbed by the land and 19% absorbed by the oceans. The absorbed energy is crucial for driving various Earth processes such as weather patterns and the water cycle.
The heat of fusion for water is the amount of energy that must be absorbed for water to what?
Melt.
