In the classification of matter, how would u classify air

your answer is "the 1950's"

ever get the answers? im stuck on this as well

i don't have a definite answer, but i would assume not based on my experiences with my friend when we both were taking a spanish course; however, it would probably still be to your benefit to look at what questions she received, just in case. a language course and a science course differ greatly, after all.
