It depends on the kind of plastic but mostly (I'd think) plastic is a better insulator for heat transport
cracks in glass travel at over three thousand miles per hour
it is glass because in my science cass at high school earlier this year we were told it travels fastest through solid, liquid, then gas. This is because in a solid the particles are closer together and then liquid then gas. So it is glass. Also Sound travels slower in air (a gas) because the particles it relies on to transmit the sound are spread out further. In liquids and solids however, the particles are less spread out and therefore the sound can transmit faster.
yes because light will have to go through the coloring.
it travels faster in water because it is less optically dense then acrylic
The heat conductivity of a container will influence the rate at which its contents lose or retain heat. Aluminum being a metal is a good heat conductor (better than glass or plastic at least) and would allow ice cubes stored in it to absorb heat more readily than the other two.
it travels faster through air.
i dont know but the sound will stay more in glass
The denser the medium, the faster sound travels through it. Glass (silicon oxide) is fairly dense, and sound waves propagate through it faster than they do through air or water.
Yes it can. Unless the plastic and/or glass is too thick. Some types of glass and plastics make it harder for light to go through. ----------- The question is: Can light pass througth plastic or glass? The answer has to be either "both" or "glass", instead simply saying "yes"
Its because gold has a greater mass than glass
bounces of glass
Glass is see through and is better quality than plastic. Plastic is not as see through as glass anyway.
No, slower.
window, because sound travels fastest through solids, liquids second, and gases last.
yes it will
It depends on the composition of each of them.
glass, plastic, crystals (although a crystal wil lallow light to pass through it, it will also diffract the light)
