The molar heat capacity of water at constant pressure,CPis 75J K-1mol-1. When 10 kJ of heat is supplied to 1 kg water which is free to expand, the increase in temperature of water is

Options:

Answer:
A
Solution:

q m =mcΔT
qm=10 kJor10000 J, m=1000g
c=75 J K-1mol-1. Number of moles=100018=55.5 mol
ΔT= 10000 55.5×75 =2.4K
