(See Appendix / for specific heat data) addition of 50 ml, of 2 02 M NaOH to 50 mL of 00 3AIDExplanation / Answer
Compared to metals, water has high specific heat
Specific heat is the amount of heat required to raise the temperature of 1 Gram of water by 1 degree centigrade.
As water is a universal liquid with prominent Hydrogen bonding, it requires more heat to raise the temperature
Where as such bonding is absent in metals.
The second reason is : in metals, metallic bond is there between atoms, which is weaker than the covalent bond in water molecules. Hence metals require less heat energy to raise their temperature ( less specific heat).
