Why is the specific heat of water 1 Cal/g*°C?

The heat capacity of water is 1 cal/g/C degree, the heat capacity of ethanol is 0.58 cal/g/C degree, and the heat capacity of amonia is 1.23 cal/g/C degree. which of these molecules will increase it's tempreature first, if an equal amount of heat was added to an equal amount of substance at an equal rate? (Amonia, Water, Ethanol)
