Propane (C3H8) is used for heating water for domestic supply. assume that for 150kg of hot water supply per day must be heated from 10oC to 65oC. What moles of propane is used for heating this amount of water ?
(DeltacH for propane = -2050 KJ/mol , c for water = 4.184 x 10-3 )
What is the meaning of thermodynamic function?
