Question
12.
An 1855 grams sample of water, initially at 28.6°C, was heated under a pressure
of 760 Torr to obtain the same mass of water at 166.0°C. The following data is available for
C =2.10 J/g°C
Cmam = 2.00 J/g°C
water: Allsion=6.02 KJ/mole
AHup
Cwnur = 4.18 J/g°C
%3D
= 40.7 KJ/mole
(a)
Draw the temperature profile for the above process in the space provided below.
(b)
Calculate the total amount of heat, in kilojoules, required for the above process.
(c)
What is the energy in Kilocalories and is it exothermic, endothermic; or adiabatic?
