Question
An experiment takes 10 minutes to raise the temperature of water in a container from 0oC to 100oC
and another 55 minutes to convert it totally into steam by a heater supplying heat at a uniform rate.
Neglecting the specific heat of the container and taking specific heat of water to be 1 cal / g oC, the
heat of vapourization according to this experiment will come out to be :
and another 55 minutes to convert it totally into steam by a heater supplying heat at a uniform rate.
Neglecting the specific heat of the container and taking specific heat of water to be 1 cal / g oC, the
heat of vapourization according to this experiment will come out to be :
Options
A.560 cal/ g
B.550 cal / g
C.540 cal/ g
D.530 cal/ g
Solution
Pt = mCᐃT
P × 10 × 60 = mC 100
P × 55 × 60 = mL
L = 550 cal./g. Option (2)
P × 10 × 60 = mC 100
P × 55 × 60 = mL
L = 550 cal./g. Option (2)
