What requires more energy the latent heat vaporisation of water or the latent fusion of ice?
The latent heat of vaporisation of water requires more energy. This is because on melting, the intermolecular bonds in water are only weakened whereas on boiling, the bonds are completely broken, which requires a larger amount of energy.
When water boils at 212 degree is only absorbing latent heat?
When water boils at 212 degrees Fahrenheit (100 degrees Celsius), it absorbs latent heat, specifically the latent heat of vaporization. This energy is required to break the intermolecular bonds between water molecules, allowing them to transition from the liquid phase to the gas phase. While the temperature remains constant during boiling, the absorbed energy does not increase the water's temperature but facilitates this phase change. Thus, at boiling point, water is indeed primarily absorbing latent heat.
When a substance changes state latent heat is?
Latent heat is the amount of energy absorbed or released by a substance during a phase change without a change in temperature. For example, when ice melts into water, it absorbs latent heat, and when water freezes into ice, it releases latent heat. This energy is crucial for processes such as melting, freezing, boiling, and condensing, as it facilitates the transition between solid, liquid, and gas states.
When water at F boils it is only absorbing latent heat?
The water has already reached the 212 degree boiling point. At 212 degrees the water can exist as either a liquid or a vapor. Absorbing the latent heat pushes liquid to the vapor state without any change in temperature.
How much energy is transfered when 1gm of boiling water at 100c condenses to water at 100c?
When 1 gram of boiling water at 100°C condenses to water at the same temperature, it releases energy in the form of latent heat of vaporization. The latent heat of vaporization for water is approximately 2260 joules per gram. Therefore, when 1 gram of steam condenses, about 2260 joules of energy is transferred to the surroundings.
Does steam has highest latent heat than boiling water?
Boiling water has a lower latent heat than steam. Steam is the transition from liquid to gas for boiling water. If by boiling water you mean liquid water at the temperature of 100 degrees Celsius then yes, steam has a higher latent heat.
Why is the latent heat of vapourization of steam is more than that of boiling water?
Because steam is hotter than boiling water.
What requires more energy the latent heat vaporisation of water or the latent fusion of ice?
The latent heat of vaporisation of water requires more energy. This is because on melting, the intermolecular bonds in water are only weakened whereas on boiling, the bonds are completely broken, which requires a larger amount of energy.
Why temperature does not rise even if water is heated as its boiling point?
In this first heat boil the water at its boiling point that is 100 degree Celsius, when the temperature is reached then heat supplied to water not boils the water it is used to change the state of the matter means heat is used to overcome the forces of attraction to change its state and the heat is latent heat of vaporisation.so this is latent heat (hidden heat) which not increase the temperature for some time.
Why in ice cube at 0 degree Celsius is much effective in cooling a drink that the same mass of water at 0 degree Celsius what is the formula?
Latent heat of the ice, liquid water has no latent heat reserves. Perhaps at freezing we should call it "latent cold" but thermodynamics has always referred to it as latent heat whether at boiling or freezing. +++ It is latent heat because the water (liquid or ice) at freezing-point (0ºC) still contains heat energy as its temperature is at about 217ºK.
Why does the temperature stops rising during melting and boiling point?
Because the latent heat of fusion and latent heat of vaporization are very high
Amount of heat used to change from one state to another?
Known to be the latent heat of evaporation or latent heat of fusion in case of boiling and in case of freezing respectively.
When water at F boils it is only absorbing latent heat?
The water has already reached the 212 degree boiling point. At 212 degrees the water can exist as either a liquid or a vapor. Absorbing the latent heat pushes liquid to the vapor state without any change in temperature.
What late heat mean in HVAC?
All pure substances in nature are able to change their state. Solids can become liquids (ice to water) and liquids can become gases (water to vapor) but changes such as these require the addition or removal of heat. The heat that causes these changes is called latent heat. Latent heat however, does not affect the temperature of a substance - for example, water remains at 100°C while boiling. The heat added to keep the water boiling is latent heat. Heat that causes a change of state with no change in temperature is called latent heat. Appreciating this difference is fundamental to understanding why refrigerant is used in cooling systems. It also explains why the terms 'total capacity' (sensible & latent heat) and 'sensible capacity' are used to define a unit's cooling capacity. During the cooling cycling, condensation forms within the unit due to the removal of latent heat from the air. Sensible capacity is the capacity required to lower the temperature and latent capacity is the capacity to remove the moisture from the air.
How much heat (calories) must be applied to a 10ml beaker filled with boiling water in order to vaporrize the water?
I guess none. Why? The given is that the water is boiling -- it is turning into vapor.
What is the value of latent heat of vaporization of water?
The latent heat of vaporization of water is approximately 2260 kJ/kg at standard atmospheric pressure and temperature. This is the amount of energy required to change 1 kg of liquid water at its boiling point into steam at the same temperature.
Is the amount of heat required to boil 1kg of water equal to the amount of heat required to melt 1kg of ice?
No, the amount of heat required to boil 1kg of water is much higher than the amount of heat required to melt 1kg of ice. Boiling water requires additional heat to overcome the latent heat of vaporization, while melting ice only requires heat to overcome the latent heat of fusion.
