Answer:
D Predicting the volume of a gas by its Temp and preasure
Step-by-step explanation:
1: not C, took the Plato test and it was wrong
C DOES seem like the answer, but determining if an element is a metal or non-metal deals with the molecular structure of said element as well as the different components meaning its more of a chemistry based task
2: the answer choice D refers to the measurement of volume and temp, these are tied to physical traits and therefore, is a task based on the understanding of physics
*SIDENOTE* a good way to tell in this case is process of elimination, we know that option A involves a more chemical style task, referring to the measurement of the acidity of said substance, same goes for option C for it deals with the molecular structure of a solution
