A indicates foam with a more fluid consistency.
A. longer drain rate
B. shorter drain rate
C. longer expansion rate
D. shorter expansion rate
Which of the following statements is correct?
Answer (2)
A foam with a more fluid consistency corresponds to a shorter drain rate, as it retains air longer and is more stable. Conversely, a longer drain rate indicates a denser and less fluid foam. Therefore, the correct answer is B. ;
The correct answer is B. shorter drain rate, indicating that a foam with a fluid consistency retains air longer and demonstrates more stability. This means it drains liquid slower than denser foams. Understanding drain and expansion rates helps clarify foam properties.
