How does plastic foam reduc heat loss?
Plastic foam consists of bubbles containing air or gas. Those bubbles are poor conductors of heat, and reduce the transfer of heat from warmer to cooler areas.
What are some insulaters of heat?
air,wool garments, plastic foam cups,rubber,wood,cotton
Why is plastic a good thermal insulator?
It Isn't. At least, not in Solid form. Plastic sprayed into a closed-cell foam, though, is an excellent insulator. Each "capsule" of gas or air is separated from each other by a miniscule cobvering of plastic; slowing heat transfer. Newer refrigerators have the foam sprayed in to fill all crevices. The R-value will give you its efficiency: R-34 is twice as good as R-17, etc.
How is a foam coffee cup a good insulator?
The foam contains air, which is a poor conductor of heat.
How does foam reduce convection?
by the air pockets
Does plastic keeps liquid hotter than a foam container or a glass container?
Foam container will keep it hotter. The air bubbles in the foam act as an insulator.
How is plastic foam is a poor conductor of thermal energy?
they have a very large amount of air present in them, plastic is a bad conductor
How does plastic foam reduc heat loss?

Is plastic or Styrofoam the poorest conductor of heat?
The answer to this question depends on the magic word NIC. NIC is short for non-intercellular. This means that the tiny cells within the foam do not connect with each other. The foam does not soak up lots of water. You can't blow air through it. A plastic foam which is NIC is a very poor conductor of heat - a good insulator. A plastic foam which is intercellular is not a good conductor, but it is nowhere near as poor as NIC foam. Its best use is as a sponge for soaking up water.

Whether plastic foam which contains pockets of air would be a good conductor or a good insulator.?
Because it fills heat slowly
Why is plastic foam good at reducing heat loss?
It fills in spaces where air can penetrate and your conditioned air can escape. It is also great for keeping insects from entering your home.
How do dirt bike air filters work?
A dirt bike uses a foam filter (some filters have a second coarse outer layer) over a plastic frame. The plastic frame keeps the filter stretched tight around the air intake for the carb. The foam filter is oiled lightly and dirt and particles stick to the oil on the outside of the filter.
What is air core coax cable?
Air core coaxial cable has the dielectric insulation between the braid and center conductor supported by a partially hollow plastic spacer. By replacing any solid plastic with air or partially air the losses are reduced and velocity of propagation is increased.
How do you change the oil filter on a 2006 Passat?
replacing oil Inner Air filter for 2006look under the glove box, remove the two plastic screws (no tool needed, just unscrew by hand)remove foam coverlocate the vented plastic cover to the left and slide it to the right.the air lifter is located in this compartment. just pull and remove. Note: pay attention to how it came out so you can place the new filter in the same way. Best of luck!
Is foam the ones for crafts a good heat insulator?
Foam is a good insulator because air is not that good at conducting (meaning that it doesn't easily transport heat or cold) in relation to other materials. As foam consists of many tiny plastic pockets trapped with air it both stops convection and prevents conduction.
Is the foam from the sea a compound mixture or an element?
The foam of the sea is a mixture, as is seawater itself. The foam differs from the seawater by containing dispersed as well as dissolved air. The dispersed air forms the bubbles of the foam.
