you want to understand temperature. which of the following would you study?
A. the heaviness of different objects
B. how much air a balloon can hold
C. a glass of water and a tray of ice
D. how many marbles fit into a box
It would definitely not be A and D so those two are out. B isn't talking about temperature so that one is also out. The only remaining answer would be C which would be the correct one.
