Question

Two steel samples, made from the exact same material, are investigated in an impact test at different temperatures of 25C and -25C. the first test yeilds a high energy absorption of 140J and the second test (Cooled Sample) shows an energy absorption of 10J.

In your own words (200 Minimum), explain the difference between both tests. Your answer should include the name of the effect and conduct test, as well as explain the implications this has had if we want to use the material to build an icebreaker for an expedition to the polar circle.
