Sci-Investigation 6
Invest 6: insulation
| question | answer |
|---|---|
| transfer of kinetic energy | conduction |
| energy always transfers from | high energy particles to low energy particles |
| material that can reduce energy transfer | insulation |
| a space containing no particles of air or anything else | vacuum |
| uses 2 layers with a vacuumed space in between as an insulator | thermoses |
| true/false: a vacuum has several particles to transfer between space and solids | false, a vacuum has no particles to transfer energy between the liquids and its environment |
| what are some (everyday) insulators | -doubled paned window (houses) -water bottle/thermos -coolers/ice chest -building insulation (fluffy&pink) -winter clothes/jacket/blanket |
| recap! | -insulation keeps hot in and cold out -vacuum -conduction -insulation -thermos |
| how do insulators work | -the better the insulator the slower energy is transferred |
| how do vacuums work | -type of insulator |
