Question

When 1.9 × 10⁴ J of Heat is supplied to 2Kg of paraffin at 12 °C in a saucepan, the temperature increases to 16 °C. Calculate the specific heat capacity of paraffin.

Answer 1

Answer

The specific heat c is a property of the substance; its SI unit is J/(kg ⋅ K) or J/(kg ⋅ ºC).  Calculating the Required Heat: Heating Water in an Aluminum Pan QAl = mAlcAlΔT = (0.500 kg)(900 J/kgºC)(60.0ºC) = 27.0 × 104 J = 27.0 kJ.  Calculate the temperature increase of 100 kg of brake material with an average
