‘Dry Ice’ is _____________ .
A.
B.
C.
D.
Answer & Solution
Solution:
Dry ice is
frozen carbon dioxide. A solid dry ice has a surface temperature of -109.3
degrees Fahrenheit (-78.5 degrees C). Dry ice also has the very nice feature of
sublimation as it breaks down, it turns directly into carbon dioxide gas
rather than a liquid. The super-cold temperature and the sublimation feature
make dry ice great for refrigeration.
