Jeff,
I'm not a scientist, but have worked in science ed for a number of years; what concerns me about the statements is that they support the misconception, very common among children and adults, that "air" is a unified thing of its own, not a mix of gases and particles. Instead, this could be an opportunity to dispel those misconceptions by presenting the info about each gas in the context of the larger idea of air.

> '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)
