one kilogram staem condensed what is weight
1 kg of steam at 373 K contains more heat than 1 kg of water at 373 K because steam has a higher specific heat capacity and latent heat of vaporization than water. This means more heat energy is required to convert water at 373 K into steam at 373 K.
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.
The difference is the evaporation heat (or the 'equal' condensation heat)
A gram of water and a gram of steam are attracted by the Earth with equal "heaviness". Steam is less *dense* than water, until you get up to thousands of atmospheres of pressure.... then it doesn't seem to matter.
The heat required to convert water to steam is known as the latent heat of vaporization. It is around 2260 kJ/kg at standard atmospheric pressure. This energy is needed to break the intermolecular bonds in liquid water and convert it into vapor.
1 kg of steam at 373 K contains more heat than 1 kg of water at 373 K because steam has a higher specific heat capacity and latent heat of vaporization than water. This means more heat energy is required to convert water at 373 K into steam at 373 K.
The amount of heat required to convert 1 kg of steam to water at its boiling point is known as the latent heat of vaporization. For water, this amount is approximately 2260 kJ/kg.
Latent heat of evaporation of water to steam is 2270 KJ/Kg
If the water content of the steam is 5% by mass, then the steam is said to be 95% dry and has a dryness fraction of 0.95.Dryness fraction can be expressed as:ζ = ws / (ww + ws) (1)whereζ = dryness fractionww = mass of water (kg, lb)ws = mass of steam (kg, lb)GAJANAN Nalegaonkar
The answer will depend on the units for the temperature.
for converting cubic meter to ton , density or specific volume is needed. specific volume unite is m3/kg. steam cubic meter/ (cubic meter/kg)= steam (kg ) /1000= tone of steam
The heat of vaporization for mercury is about 59.11 kJ/kg. To convert this to joules/kg, multiply by 1000 to get 59,110 J/kg. Therefore, for 0.06 kg of mercury, the energy released when condensed to a liquid at the same temperature would be 0.06 kg * 59,110 J/kg = 3,546.6 Joules.
The answer will depend on the starting temperature of the water. It will also depend on the pressure.
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.
To calculate the molality of NaCl in water, first, determine the number of moles of NaCl by dividing the mass of NaCl (0.2 kg or 200 g) by its molar mass (approximately 58.44 g/mol). Then, divide the number of moles of NaCl by the mass of the solvent (water) in kilograms (3 kg). The formula for molality (m) is m = moles of solute / mass of solvent in kg.
The difference is the evaporation heat (or the 'equal' condensation heat)
will density of water is equal to density of steam at high pressures and temperatures
