How can I calculate the energy required to heat 50g from O Celsius to water vapor at 100 Celsius?

OpenStudy (anonymous):

q = mcΔT, So we know everything but the constant which is 4.21 i think? might want to check on that

OpenStudy (anonymous):

then you are going to need to use this one to see how much it takes to push the phase change from water to steam. q = nΔH

OpenStudy (anonymous):

c = 4.184 J/(g oC) is what c equals for the first equation

OpenStudy (anonymous):

my teach attached these to the packet: Cwater=1 cal/g Celsius, C ice = 0.5 cal/g Cel, C vapor= 0.4 cal/ g Cel, H vap=cal/g & Hfus=80 cal/g

OpenStudy (anonymous):

\[q=(50g)(1 \frac{Cal}{g Celsius})(100 Celsius)=5000 Cal\]

OpenStudy (anonymous):

you still have to push the phase change and add it both of them together,

OpenStudy (anonymous):

where do i get the phase change?

OpenStudy (anonymous):

from 100 degrees cel you have to get a phase change going from water to steam
