Question

The molar heat capacity of water at constant pressure, $C_{P}$ is $75JK^{- 1}mol^{- 1}$ when 10 kJ of heat is supplied to 1 kg water which is free to expand, the increase in temperature of water is

Answer 1

Solution

: $q_{m} = mc\Delta T$

$q_{m} = 10kJ$ or 10000 J, m = 1000 g

$c = 75JK^{- 1}mol^{- 1}No.ofmoles$

$= \frac{1000}{18} = 55.5mol$

$\Delta T = \frac{10000}{55.5 \times 75} = 2.4K$
