What is the specific heat of water in J kg K?
4184 joules
The SI unit of specific heat capacity is joule per kelvin per kilogram, J⋅kg−1⋅K−1. For example, the heat required to raise the temperature of 1 kg of water by 1 K is 4184 joules, so the specific heat capacity of water is 4184 J⋅kg−1⋅K−1.
How do you calculate the heat of vaporization of water?
The molar heat of vaporization for water is 40.7 kJ/mol. To get the heat of vaporization, you simply divide the molar heat by 18.015 g/mol.
What is the specific heat of water at 100 C?

What is heat of vaporization Brainly?
Answer: heat absorbed when a liquid vaporizes specifically : the quantity of heat required at a specified temperature to convert unit mass of liquid into vapor.
What is the standard molar heat of vaporization at 37 C?
The heat of vaporization of water at 100°C is 2.26 kJ/g; at 37°C (body temperature), it is 2.41 kJ/g.
What is the heat capacity of 175 g of liquid water?
The heat capacity of 175 g of liquid water is 732.55 J/°C.
What is the specific heat of water in imperial units?
What is the specific latent heat of vaporization?
Specific Latent Heat of Vaporisation is the energy required to change the state of 1kg of a substance from liquid to gas.
What is a substance heat of vaporization?
The heat of vaporization is defined as the amount of heat needed to turn 1g of a liquid into a vapor, without a rise in the temperature of the liquid.
What is latent heat of vaporisation Class 9?
The term latent heat of vaporisation can be defined as the amount of heat needed for the conversion of 1kg of liquid at its boiling point to gas at same temperature.
What is the specific latent heat of water?
Water has latent heat of vaporization of 540 calories per gram, the amount of heat energy that is necessary to convert 1 g of liquid water at 100°C to steam at 100°C, or 40.71 kJ/mol or about 2,260 kJ/kg water.
What is the unit of latent heat of vaporization?
In case of liquid to gas phase change, this amount of energy is known as the enthalpy of vaporization, (symbol ∆H vap; unit: J) also known as the (latent) heat of vaporization or heat of evaporation. Latent heat is the amount of heat added to or removed from a substance to produce a change in phase.
What is the definition of high heat of vaporization?
To say that water has a high heat of vaporization means that it takes a lot of heat energy to change its phase from liquid to solid. The reason why is that water forms relatively strong hydrogen bonds between the molecules. Within each molecule, the oxygen atoms are far more electronegative than the hydrogen atoms,…
What is the enthalpy of vaporization?
The enthalpy of vaporization, (symbol ∆H vap) also known as the (latent) heat of vaporization or heat of evaporation, is the amount of energy (enthalpy) that must be added to a liquid substance, to transform a quantity of that substance into a gas. The enthalpy of vaporization is a function of the pressure at which that transformation takes place.
