Why is a polystyrene container used to store ice cubes?

Because polystyrene has certain thermal properties that can be used in order to store things and maintain their temperature.

When you store ice cubes in polystyrene containers they won't melt and they'll keep cold because the cold they'll generate in the container wont escape, and the heat from outside wont come in.

Hope it helped,

you need to provide a picture, otherwise i can't tell you.

if you can provide one, i'd be more than happy to you with this!

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
