If the aluminam block is initially at 25C, whut is the final temperature of the block afer fie evageralion of the alcohol? Assume that the heat reguired for the vaporization of tho alcohol cemas enty froin ale alaminum block and that the alcohol vagorizes at 25C. The heat of vaportzation ef the alcahol at 25CC. is 45.4kJ/mol the specific he at of aluminum in 0.903J/g. C How much heat (in kal) is evolved in converting 2.00mol of steam at 1337C to ice at 43C ? The heat capacity of steam is 2.01J/(g; C ), and that sna of ki is 209J/(sC) Express your answer in kilojoules to three significant figures
