A Wankel engine uses aluminum in its housing structure, which has a greater coefficient of thermal expansion than the material used in a piston engine, which is often cast iron. such a feature prevents an overheated Wankel engine from seizing, an especially desirable attribute in an aircraft engine. the coefficient of 23*10^-6 m/m C. what is the final volume of a 0.051 m^3 Wankel engine if its initial temperature is 427 C and the final temperature is 538 C?
