A class IIIA liquid is a type of hazardous material classified by the U.S. Department of Transportation. It includes low hazard flammable liquids with flash points between 140°F and 199.4°F, such as diesel fuel and motor oil. Transporting these liquids requires adherence to specific regulations for safety.
base in my experience.... because of the gravity of the earth...
liquids are not fluids because a fluid is a class based on motion not a class based on a state of matter like a liquid.
because in IIIA group d-orbital interduce so Ga has greater I.P value than Al and the atomic radius of Boron and Al are nearly about same and ionic radius of Al and Ga are nearly about same as a result there is not regular change occurs in the properties of IIIA group.
The ionization energy drops from group IIA (alkaline earth metals) to group IIIA (boron group) due to the increasing atomic size and the presence of additional electron shells. In group IIA, the outermost electrons are in the same shell and experience a strong effective nuclear charge, making them harder to remove. However, in group IIIA, the introduction of a new electron in a higher energy level results in increased electron shielding and a weaker attraction to the nucleus, thus lowering the ionization energy.
An incombustible gas is one that does not burn or explode.(Incombustible means something that cannot be burnt.)Some good examples of incombustible gases arenitrogen (which is fortunate, because 78% of the air is nitrogen, and if nitrogen was combustible, the air would explode!)carbon dioxideargon
It's a class K0-IIIa .
NFPA 30 gives the following definitions and examples.definition:Class IIIA - Flash Point equal to or greater than 140°F, but less than 200°FClass IIIB - Flash Point equal to or greater than 200°Fcommon examples:Class IIIA - Home Heating OilClass IIIB - Cooking Oils, Lubricating Oils, Motor Oil
Maximum - twenty years imprisonment, or twenty-five thousand dollars fine, or both Minimum - one year imprisonment
Class 3 Flammable Liquid label
Class 3 Flammable Liquid label
The element with the highest first ionization energy in group 14 is carbon.
Methanol is a flammable liquid and falls in hazard class 3.
Check the label. If it is marked "Class II", "Class IIIa", "Class 2" or "Class 3R", it is safe. All of those have power less than 5 milliwatts. The "Class II/Class 2" pointers are the safest--they are limited to 1 milliwatt. Do not use blue or green laser pointers as toys, even if they are rated Class 3R.
Burning liquid fires require a U.L. Class B fire extinguisher, or ABC, or BC.
