Final answer:
Liquids are divided into different classes based on their flash point temperatures. The flash point is the lowest temperature at which a liquid can produce enough vapor to form an ignitable mixture with air. Class IB and Class IIIA have flash points below 100 degrees F (38 C).
Step-by-step explanation:
Liquids are divided into different classes based on their flash point temperatures. The flash point is the lowest temperature at which a liquid can produce enough vapor to form an ignitable mixture with air. In this case, we are looking for liquid classifications with flash points below 100 degrees F (38 C). The correct answer is Class IB and Class IIIA. Both of these classes have flash points below 100 degrees F (38 C).
