An important chemical property of inorganic acids is that when they react with metals, they give off hydrogen gas in conjunction with the formation of a salt
HCl is a mineral acid while Mg is a metallic substance
So the reaction between this metal and the mineral acids will give the needed hydrogen gas to be produced
because water is loosely packed but when it is cold it becomes closely packed in order to form ice and thus the force attraction between them also increase.
