Solid > Liquid > Gas.
Temperature is a measure of the kinetic energy (K.E.)of the molecules present in a substance. Among the three states, the solid form has the lowest value of K.E. and the gas the highest, as in the solid state molecules are closely packed within a limited space for a particular substance. So more heat is required for the solid than the liquid, and the liquid needs more than the gas, to increase the temperature of a specific mass by one degree.

The specific heat of water is 1 calorie/gram °C = 4.186 joule/gram °C which is higher than any other common substance. As a result, water plays a very important role in temperature regulation. The specific heat per gram for water is much higher than that for a metal.
