Metal reactivity with hot water VS HCL - Chemistry Stack …

Does being able to react with hot water take more metal reactivity than being able to react with HCl? To me, it seems like a metal would need to be more reactive to be able to react with hot water since HCl is a very strong acid and so should theoretically be able to react with more metals, but I am not so sure.
