I'm trying to verify some facts another department has printed up from various internet sources.  I can't seem to get past, or find good verification, of these two statements:
'Air becomes liquid at about minus 190 degrees Celsius.'  (for clarity, wouldn't a gas composing air need to be specified, like nitrogen at -196 C)
'Liquid air looks like water with a bluish tint.'  (this confuses me, as I always thought of air as a 'fluid,' unless this is in reference to liquid oxygen or liquid nitrogen)
Would anybody print up these statements and put them in their science center or museum?  Thanks for any input.
