That 1500 kJ of energy were transferred to water at 20.0°C. Heat capacity (c) for liquid water is 4.18 J/g C. mass of water could be brought to the boiling point is 4485 g.
given that :
heat energy = 1500 kJ
heat capacity , c = 4.18 J/g °C
initial temperature = 20.0°C
boiling of water ,final temperature = 100 °C
Q = mcΔT
m = Q / (cΔT)
m = 1500 / ( 4.18 × ( 100 °C - 20 °C )
m = 1500 / 334.4
m = 4.485 kg = 4485 g
Thus, That 1500 kJ of energy were transferred to water at 20.0°C. Heat capacity (c) for liquid water is 4.18 J/g C. mass of water could be brought to the boiling point is 4485 g.
