An electric current of 3Aflowing through an electric heating elements of resistance 20 embedded in 1,000g of an oil raises the temperature of the oil by 10oC in 10 seconds then the specific heat capacity of the oil is
Heat energy = Electrical energy
mc\(\Delta\)\(\theta\) = I\(^2\)Rt
1000 x c x 10 = 3 x 3 x 20 x 10
0.18Jg\(^{-1}\)ºC
