Heat of vaporization of water = 540 cal/g m=1000 g energy supplied = 5.4 kcal=5400 cal T1=T2=100 deg. C so all energy is used to convert to steam mass of steam produced = 5400 cal /(540 cal/g) =5400/540 cal *g/cal =10 g
A kind of transformation known as phase change, in this when one is performing phase change, the component remains at the similar temperature all through the phase change. This is illustrated as whether one is heating or cooling the substance down. The heat subtracted or added relies upon the mass of the substance or the Latent Heat of the substance.
The heat added or subtracted is given by the formula:
Q = mL
Q is heat, L is latent heat of vaporization, which is 539 kcal/kg, and m is the mass of steam
