well it depends on how many pounds of each but they both weigh the same
The answer will depend on the size of the bottle and what it is made of - glass or plastic.
Glass
Glass is a better insulator than plastic. Plastic is used on wire for insulation purposes because of its flexibility, where as glass is not. Glass is used as insulators for holding wires to cross arms on power poles as plastic would not stand up to the weather year after year.
Assuming they are the same or similar shape and volume, water in glass would freeze first, then plastic then foam. Foam allows transfer of heat out of water more slowly than plastic and the glass probably has the highest rate of heat radiation of the three.
Glass and plastics are not good conductors of electricity.
Plastic skylights weigh less than glass and can be replaced easier. Using plastic instead of glass lowers the fabrication price and allows for more recycled items to be used in its construction.
Because the plastic containers WEIGH less than glass.
Glass is more durable.
Plastic is less dense than glass, so normally a plastic cup is considerably lighter than a glass cup, although in theory a very small glass cup could weigh less than a very large plastic cup.
There is no difference in the effectiveness of glass or plastic. Glass is more fragile for breaking but easier to keep clean, plastic is safer for not breaking, and harder to keep clean longer. It is a personal choice.
Yes, both glass and plastic bottles can be recycled, although which kinds of plastic depends on the recycling program in your area. Check out this article for more information: http://kansascity.about.com/od/communityinformation/p/RecycleKC.htm.
I believe so. If you had glass pieces and plastic pieces, and you threw them all in water, the plastic would float while the glas would sink. I hope this helped. ~;]]
Water "wets" plastic more than glass, giving a lower reading
The advantage of plastic is that it is lightweight and more impact resistant than glass. The advantage of glass is that it is scratch resistant and provides the clearest possible vision.
When It comes to decanters, I always prefer glass over plastic. Glass appears more dignified and gives your wine or spirits an extra sparkle.
Glass is so much more classy than plastic. Or is that not what you meant?
Plastic shelving would be better in a freezer than glass because the extreme cold would make the glass more brittle and thus more likely to break.
