Calculate the amount ofheat required to convert 15 g water at 100 celcius into steam |
|
Answer» Answer: The total heat rewired is the SUM of the heat in rising the temperature of the water to 100 degrees from 25 degrees and LATENT heat as there is a phase CHANGE from liquid to valor at 100 degrees. Q=mC(t2-t1) + mL C=Specific heat of water m= mass of water L= Latent heat t2-t1= temperature change Q= 2.5 × 4.814 (100–25) + 2.5*334 = 1737.63 |
