    just about all substances. pick anything..... say, gummy bears.

    examples of substances that cool when more heat is added are very rare.

    clusters of Na atoms for example

    some models of star core collapses (i.e. supernova explosions) can involve a negative heat capacity too.

    but in general (i.e. for any substance you are familiar with): add heat, temperature increases. remove heat, temperature decreases.

    cheers

    not one of the solutions till ultimately now are somewhat nicely suited. u=0 and v=0 implies the physique replaced into at relax in the commencing up, and is at relax on the tip. some project like a automobile that one and began at living house, and ended up after it gradual in the parking zone of the procuring mall! Or the motor vehicle that remained at living house in the storage all the time. So, what are you able to declare - on the main that the common acceleration replaced into 0.
