The change in length for an object that is one meter long subject to a 10 degree change in temperature will be on the order of:. a. whole meters.
b. whole millimeters.
c. fractions of a millimeter.
d. whole centimeters.

It should be d if not then c

I'm not sure what your asking buddy.. but i know that you can weld two peices of steel by pure force and pressure.

The relationship of both of them

If the heat engine is a perfect carnot cycle engine, thenefficiency = (t2-t1)/t2   where t1=temperature of cold reservoir ( ° k) = 135            t2=temperature of hot reservoir ( ° k)   = 325thereforeefficiency = (t2-t1)/t2 = (325-135)/325 = 0.5846 = 58%  note: this is the theoretical maximum efficiency of a perfect heat engine.   real-life engines do not achieve this value.
