Solution: Given parameters are, Q = 400 k.cal. I know that methanol boiling temperature is 64 °C and water boiling temperature is 100°C, and it will be necessary to use two 'kinds' of heat, one for taking the component from 25°C to the boiling temperature, and another called the latent heat, for the phase change. FIRST AID: CALL A PHYSICIAN. Latent Heat of Vaporization of Oxygen is 3.4099 kJ/mol.

46.7185 lb/ft³. Heat of Vaporization of Ethanol. The nanofluid was prepared by using an ultrasonic homogenizer without any surfactants. Determine the latent heat of 5kg substance if the amount of heat for a phase change is 300 k.cal. Component M = 5 kg.
Latent heat can be understood as energy in hidden form which is supplied or extracted to change the state of a substance without changing its temperature. Avoid contact with eyes, skin, and clothes.
Formula for latent heat is given by, L = Q / M. L = 300 / 5. L = 60 k.cal/kg.
