Q:which gases are released when plastic is burnt?
Plastic can be converted as a fuel since they are usually hydrocarbon-based and can be broken down into liquid hydrocarbon. One kilogram of waste plastic produces a liter of hydrocarbon.In some cases, Burning of hydrocarbons gives water and CO2 Burning plastic can release toxic fumes however . Burning the plastic polyvinyl chloride (PVC) may create dioxin. HCN is produced when foam, melamine, polyacrylonitriles, and synthetic rubber burn. The residue will depend on the plastic and how it was burnt ..
Q:Would plastic, card or paper make a better sail?
OOOPS... Someone needs to do some serious updating here... Today's technology doesn't stop at Dell or Microsoft... That is where it begins... Fact is Rigid Sails are now proving to be much, much faster then cloth. Now rigid airfoils on sailing vessels (especially on multi-hull sailing vessels) are shattering all kinds of world speed records across the water. The trick is balancing maximum strength with mimimum weight and keeping it all together. I don't really know the answer to your question - only to say that if you are building a model (either real or imaginary) a rigid sail is proven best... as to plastic, card, or paper - I would go with the one that gives the best strength ratio to the rest of my model. The site below also has a lot of links that may be helpful. Have fun! Capt. John
Q:Why does my cat chew plastic?
Hi okorder.com/.. The best thing you can do for your kitty is to keep all plastic out of reach of the cat. It will be a lot safer for your kitty. Some folks think that plastic may be attractive to cats because some of it is made with rendered animal fat. Don't know if that is true today, but it was awhile ago.

Q:can I stencil on dry plastic?
Spraying your plastic with hairspray won't work well and will peel off in a short time. You need to rough up the surface of the plastic in order for the paint to stick. Try sanding it with some medium-grit sandpaper first. Then use model paints (the kind used to paint model cars and planes and found in hobby shops), which were made for painting on plastic. And do several light coats as opposed to one heavy coat. Acrylic paints should work also, but you'll have to use a sealer over them. You might also consider using nail polish for some interesting effects. Nail polish is actually very chemically close to car paint and made to stick to both metal and plastic surfaces.
Q:Are plastic containers/ Tupperware unsafe?
No, there is no danger in heating up plastic containers. I hear a lot of silly comments about many different things also. Hell, I know a few people who still believe that microwave ovens are dangerous! Edit: Sorry Jonboy, but it seems to me that although you may have a basic concept of some plastics, you seem to have no concept as to the amount of potential leaching of materials which may occur by simple heating, or the damage that a few released molecules could possibly have on any living being. Obviously if the material melts, it was not being used properly. Even if it did it would not cause any health risk. It would mean that the container would no longer be usable for it's originally intended purpose!

Q:is plastic reactive with anything?
What kind of plastic? Plastics are polymers. Polymers are typically long strands of hydrocarbons (obviously there are various formulations). Polypropylene (yougurt containers, milk jugs) are common types... as are polystyrenes (cheap plastic glasses). Polymers are not typically reactive as there are not reactive sites like metals have. But there are definitely polymer reactions that can occur as well as incompatibilities with some materials. Draw out the structure and think about how it could react, look for those pesky valence electrons like metals have when they disassociate in water.

Q:plastic bags?
You are probably refering to two forms of the plastic polyethylene, high and low density. Low density is probably the 'greener' of the two, but it can't be by much.
