1. How much energy (in kJ) is required to completely vaporize 200.g of 25.0*C liquid water?...
Step 2: How much energy does it take to completely vaporize the boiling water? This is where you use AH because it is a phase change. Do you use AH or AH? Vaporization means the water is vaporizing (or condensing) where fusion means the water is freezing (or melting).
How much heat energy(in kJ)is needed to vaporize 84 g of liquid water at 100°C?
Part 2: Multi-Step Curves (Day 2) 1. How much energy (in kJ) is required to get a 25.0 g ice cube (water) at -10.0 C to completely melt, vaporize, and become 110.0°C vapor?
a. How much heat (kJ), at 1 atm, is required to raise the temperature of 25.0 g of liquid ethanol from -5.0°C to its boiling temperature and then vaporize all of it? Cs, liquid= 2.46J/g°C AHvap=38.6 kJ/mol b. How much heat (kJ), at 1 atm, is required to raise the temperature of 25.0 g water from 5.0°C to its boiling temperature and then vaporize all of it? Cs, liquid=4.184 /g°C AHvap=40.7 kJ/mol
