QAIPMT-2003-Ch-2682: NEET 2003 Chemistry - Class 11 AIPMT-2003-Ch-2682 Solution: The molar heat capacity of water at constant pressure, C, is…
The molar heat capacity of water at constant pressure, C, is . When 1.0 kJ of heat is supplied to 100 g of water which is free to expand, the increase in temperature of water is
Multiple Choice Options
- A 2.4 K
- B 4.8 K
- C 6.6 K
- D 1.2 K
Step-by-Step Verified Solution
As we know, q = nC _ T
q = 1.0 kJ = 1000 J
C = 75 JK �1 mol �1
m = 100 g _ Number of moles = 100 18 g mol �1
1000 = 100 18 _ 75 _ _ T
_ _ T = 10 _ 18 75 K
_ _ T = 2.4 K
