WebA mass m of ice at a temperature of –5 °C is changed into water at a temperature of 50 °C. Specific heat capacity of ice = ci Specific heat capacity of water = cw Specific latent heat of fusion of ice = L. Which expression gives the energy needed for this change to occur? A. 55 m cw + m L. B. 55 m ci + 5 m L. C. 5 m ci + 50 m cw + m L WebThe specific latent heat of vaporisation - the heat needed to turn 1 kg of liquid into a gas at its boiling point. The heat needed is given by the equation: Heat energy to melt or boil something = mass x specific latent heat Example problems 1. Find the energy needed to change 4 kg of water at 100oC into steam at 100 o C.

WebWhen latent heat is added, no temperature change occurs. The enthalpy of vaporization is a function of the pressure at which that transformation takes place. Latent heat of vaporization – water at 0.1 MPa (atmospheric pressure) hlg = 2257 kJ/kg. Latent heat of vaporization – water at 3 MPa (pressure inside a steam generator) hlg = 1795 kJ/kg. harley davidson showa

Specific latent heat - Specific heat capacity and latent …

WebMass (m) = 5.00 kg. Temperature (T) = 80.0 K. Specific heat (c) = 1676 KJ. Now we have to convert the specific heat into Joules because it is in Kilojoules. So, the conversion is like this. 1 KJ = 1,000 J. So, 1676 KJ = … WebThe specific latent heat of water is: \ (l_ {f}=3\cdot34\,\times10^ {5}\,J\,kg^ {-1}\) for fusion (solid→liquid) or freezing (liquid→solid) \ (l_ {v}=22\cdot64\times10^ {5}J\,kg^ {-1}\) for... WebSpecific latent heat is the amount of energy required to change the state of 1 kg of a substance without changing its temperature.
