1. The problem statement, all variables and given/known data Compare the properties of a engine oil used in your lawnmower with that used in a snow blower. relate these properties to the intermolecular forces in each type of oil. 3. The attempt at a solution i think this has something to do with carbon chains and how in winter the oil may get thicker and become pasty in the engine and how in summer it may get too thin and not be able to lubricate the pistons? i am not too sure about this one. some help is greatly appreciated.
