Take equal weights of oil and water in two deep frying pans or two suitable utensils of the same size and material.   Take half a litre of water weighing 1/2 kg and take 1/2 bottle of oil weighing 1/2 kg.

Put both of them on the gas stove with the same intensity of flame (in SIM position for example). 

Observe the initial temperature in both liquids. Write them down on paper.  After every three minutes write down the temperatures of both liquids.  Dip the thermometer in the liquids for 20 seconds for the thermometer to read the temperature correctly.

After 3 readings you will observe that the oil heats up and rises in temperature faster than water.  Be cautious in selecting a thermometer which has a range from 20 deg C to 80 deg C.

This experiment proves that the rate of rise in temperature depends on the substance.

The dependency of rise of temperature on substance is called the specific heat (or heat capacity) of the substance.
     In the above experiment :  ΔQ = m s ΔT
   ΔQ, and m are chosen to be same.  So  ΔT is more for oil which has less value of "s" specific heat.
