Answer 1

Solid carbon dioxide, also known as dry ice, can be carried in either carry-on or checked baggage when used to pack perishables based on certain conditions.

Step-by-step explanation:

According to transportation regulations, solid carbon dioxide, also known as dry ice, can be packed when used to pack perishables. It can be carried in either carry-on or checked baggage, depending on certain conditions. If the quantity of dry ice does not exceed 2.5 kg per passenger and it does not release carbon dioxide gas, it may be carried in carry-on baggage. However, if the dry ice permits the release of carbon dioxide gas and has the approval of the operator, it can also be carried in carry-on baggage. If the dry ice is in checked baggage, it should be marked as 'dry ice' or 'carbon dioxide, solid' only.
