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.
