A.5kg of steel is cooled down in oil and the temperature drops from 900 degrees celsius to 27degrees celsius. The specific heat capacity of steel is 460J/kg degrees Celsius and that of oil 1.5kJ/kg degrees Celsius

Calculate the following:

1.quantity of heat lost by steel
2.mass of oil required if the original temperature of the oil is 18 degrees Celsius
