1.	The change in temperature of a substance , when a given quantity of heat is absorbed or rejected by it is characterised by the heat capacity. Define specific heat capacity, molar specific heat capacity at constant presssure and molar specific heat capacity at constant volume. Give the reason for using water as a coolant in automobile radiators.
Answer» SOLUTION :For definations, The reason for using water as a coolant is its HIGH SPECIFIC heat CAPACITY.
