question 3 of 3
3 what is one way dry ice is different from regular ice?
a dry ice forms at a colder temperature than regular ice
b regular ice melts at a higher temperature than dry ice
c dry ice works better in air fresheners than regular ice
d regular ice keeps food cold for a longer time than dry ice

Explanation:

Dry ice is solid carbon - dioxide and forms at a much colder temperature (-78.5°C) compared to regular ice (water ice) which forms at 0°C. Regular ice melts into water at 0°C while dry ice sublimates (changes from solid to gas) at -78.5°C. So dry ice forms at a colder temperature.

Answer:

A. Dry ice forms at a colder temperature than regular ice
