What are the materials used in thermal insulation? andWhat is the best material used in thermal insulation and noise?
A fun (fire cracker) one we used to make is to get two cans - one just slides inside the otherYou fill the larger with some water - and then punch a hole in the bottom of the other - slide it down into the water - and put a firecracker into the hole in the top of the smaller can - light it and runMakes a great rocketThe blast of the firecracker is contained very well against the water in the larger can - and you can blast the smaller can 30 feet into the air sometimesFire crackers are just black powder - carbon, salt peter and sulfur, and it's a fairly rapid oxidizer.
Yes you can make a rocket using an aluminum tube with powdered zinc and sulphur as a fuelit is very dangerous just as a rocket fueled with gun powder is.
Because rockets are dangerous, you need to learn about them before experimenting with themRead a textbook about rockets, then join a rocketry club, and get help from the other membersYou cannot do this by yourselfBTW the mixture that you suggest would not work.
A simple low efficiency rocket is relatively easy to make (but dangerous if you don't know what you are doing)Basically a solid fuel rocket reaction is a slow explosion, and even NASA have lost lives even after really careful research., It's best to buy ready made small rocket motors and follow ALL the safety precautions unless you dont mind loosing a few fingers etc.
Materials which are said to have thermal insulation properties if it reduce the rate of heat transfer, or the methods and processes used to reduce heat transferHeat energy can be transferred by conduction, convection, radiation or by actual movement of material from one location to anotherCommon thermal insulation materials when it comes to a buildings are: Rockwool fiber or rockwool panels extruded polystyrene or styrofoam for pipings and duct installation asbestos which is already ban Others In terms of physical body insulation, we use all styles and forms of clothings.
