1. How much heat (in kJ) is required to raise the temperature of 9.0 kg of an oil (specific heat 2.135 kJ/kg.oC) from 46°C to 245°C.

2.What is the increase in length in m of a sample of carbon fibre (coefficient of linear expansion = 7.9 x 10-6 oC-1), 26 m long if the temperature goes from 9°C to 35°C?

3.How much heat (in kJ) will it take to bring 5.6 kg of ice at -13°C to dry saturated steam at atmospheric conditions? (Refer to the Formula Book for the required physical constants)

4. How much heat (in kJ) does it take to raise the temperature of 30 kg of water at 10°C to dry saturated steam at 550 kPa?

5.How much heat is evolved when 60 kg of saturated steam of 900 kPa and 74% dryness fraction is cooled to water at 60°C?
