What are the units of specific latent heat?
specific latent heat is measured in joules per kilogram (J/kg)
What is specific latent heat of vaporisation?
Latent heat of vaporization is a physical property of a substance. It is defined as the heat required to change one mole of liquid at its boiling point under standard atmospheric pressure. It is expressed as kg/mol or kJ/kg. The heat of vaporization of water is about 2,260 kJ/kg, which is equal to 40.8 kJ/mol.
Is latent heat of fusion?
The latent heat associated with melting a solid or freezing a liquid is called the heat of fusion; that associated with vaporizing a liquid or a solid or condensing a vapour is called the heat of vaporization.
What is the specific latent heat of steam?
As the latent heat of steam at atmospheric pressure is 2257 kJ/kg the amount of flash steam produced will be 299/2257 = 0.133 kg/kg of condensate.
What is the latent heat of condensation?
Latent heat of condensation is energy released when water vapor condenses to form liquid droplets. The latent heat of condensation is defined as the heat released when one mole of the substance condenses. The energy released in this process is called heat of condensation.
What is the latent heat of ice?
The latent heat of fusion of ice is 33600 J/K. Latent heat of fusion of ice is the amount of heat required to melt a unit mass of ice from the solid-state to the liquid state.
What is latent heat of ice and water?
A total of 334 J of energy are required to melt 1 g of ice at 0°C, which is called the latent heat of melting. At 0°C, liquid water has 334 J g−1 more energy than ice at the same temperature. This energy is released when the liquid water subsequently freezes, and it is called the latent heat of fusion.
How much is latent heat of fusion of ice?
The latent heat of fusion for ice is 80 calories per gram (see calorie). This amount of heat is absorbed by each gram of ice in melting or is given up by each gram of water in freezing. The latent heat of vaporization of steam is 540 calories per gram, absorbed during vaporization or given up during condensation.
What is J kg C?
The specific heat capacity of a material is the energy required to raise one kilogram (kg) of the material by one degree Celsius (°C). The specific heat capacity of water is 4,200 Joules per kilogram per degree Celsius (J/kg°C). This means that it takes 4,200 J to raise the temperature of 1 kg of water by 1°C.
What is the specific heat of steam in J kg C?
1.996 kJ/kgK
What is the specific heat capacity of brass in J kg C?
920
