A piece of unknown material weighs 0.4 kg. It is heated to 70 °C, then transferred into a 2 kg bath of oi at 20 °C. The bath temperature eventually reaches 40 °C. Assuming that Cmaterial = 0.6 kJ/(kg-K), calculate the specific heat of the oil in kJ/(kg-K). Do not include units in your answer and write the numerical value in normal form.
