A dewar flask is used to ship which substance?

Explanation:
A dewar flask is an insulated vessel designed to store and transport very cold liquids by minimizing heat input and boil-off. It’s used for cryogenic liquids, like liquid oxygen, which must be kept at extremely low temperatures to stay in the liquid state. The other options are gases at room temperature (or are not shipped as liquids in dewars)—acetylene isn’t stored as a liquid in dewars due to instability; hydrogen gas and nitrogen gas are gases, not liquids, in typical shipping conditions. Therefore, liquid oxygen is the substance shipped in a dewar flask.
