6. 7. 8. Explain how cyclic integration relates to the Carnot cycle. Consider the normal boiling point of methanol of 64.1°C at which vaporization consumes 35.27 kJ/mol and calculate [4] the entropy of vaporization of methanol at this temperature. ii) the entropy change of the surroundings. [2] Consider two initially separate blocks of copper in an isolated container. Each block is of mass 15.0 kg, and one is at 100°C and the other at 25°C. They are placed in contact and allowed to equilibrate. Refer to the prescribed textbook Resource section for data. The plaf4capacity is to be regarded as constant over the temperature range. Calculate the total change in entropy and rationalize the result. [7] [2]
