The specific heat capacity of the oil is 2000 J/kg°C.
To calculate the specific heat capacity of the oil, we use the formula below.
Formula:
- Q = cm(t₁-t₂)............... Equation 1
Where:
- Q = Heat transfer by the oil,
- c = Specific heat capacity of the oil
- m = mass of the oil
- t₁ = Initial temperature of the oil
- t₂ = Final temperature of the oil.
Make c the subject of the equation
- c = Q/m(t₁-t₂)................ Equation 2
From the question,
Given:
- Q = 70.4 kJ = 70400 J
- m = 400 g = 0.4 kg
- t₂ = 25 °C
- t₁ = 113 °C
Substitute these values into equation 2
- c = 70400/0.4(113-25)
- c = 70400/(35.2)
- c = 2000 J/kg°C
Hence, The specific heat capacity of the oil is 2000 J/kg°C.
