Mark below all of the statments that correctly describe the physical properties of glass.

Glasses do not have slip systems.
Glasses consist of both covalent and ionic bonding.
Glasses are brittle at room temperature.
Glasses are amorphous and have no long range symmetry.
The volume of a sample of glass depends on its cooling rate.
Glasses must consist of network formers and modifiers.

  • Alan -

    What do you think. If you post your answers, someone might tell you whether or not they are correct.

  • Alan -

    I think that both
    c) Glasses are brittle at room temperature
    and
    d) Glasses are amorphous and have no long range symmetry
    apply.
    But then again, my knowledge is limited.

  • Alan -

    C and D are not correct, try again.

  • Alan -

    Someone could try C, D and F? Because it's my last chance.

  • Alan -

    "A", "E", "F" should be correct.
    but don't know others ~~

  • Alan -

    Is it the answer?

  • Alan -

    A,E and F are not correct, and C,D and F are not correct.

  • Alan -

    All together are wrong. A,C,D,E.F are wrong??????

  • Alan -

    I beleive that only the D is correct, but i tried the 3 submissions, can any one try it?

  • Alan -

    It's possible, I know that letter B is wrong because glasses consist ONLY ionic bonding.

  • Alan -

    I tried before C-D-E and B-C-D-E-F, but all the answers were incorrect

  • University of Idaho -

    Only D is not correct.

  • Alan -

    What about A and D?

  • Alan -

    I think it's possible A-C-D-E-F, can be?

  • Alan -

    AS i mentioned before (Anonymous)/ 3:36 are incorrect.

  • Alan -

    is it not easier to check if a option is correct or not. whit al of us we should be able to figure it out

  • Alan -

    D is correct,
    but the rest?

  • Alan -

    update of correct options
    BCD
    so what about AEF???

  • Alan -

    any answer?

  • Alan -

    I think all of the except E are correct. Any idea?

  • Alan -

    B isn't correct too, 'cause glasses consist only ionic bonding.

  • Alan -

    Did some one find it, B and C are correct, whats other?????

  • Alan -

    Sorry C and D

  • Alan -

    There's a chance A-C-D-F will be correct, 'cause it was the only combination we don't try

  • Alan -

    Can some one try it? i have only one chance............

  • Alan -

    I organized all the answers don't correct:

    D
    C-D
    A-E-F
    B-C-D
    C-D-E
    C-D-F
    C-D-E-F
    A-B-C-D-E-F

  • Alan -

    Additional incorrect and:
    ACDEF
    ACDF

  • Alan -

    A-B-F is wrong too

  • Alan -

    I beleive A C D is correct................can some one try it????

  • Alan -

    ACD IS WRONG

  • Alan -

    Thanks Flou, maybe all is wrong!!!! did any one tried it, i beleive it is unpossible duo to we know that at least C and D are correct.

  • Alan -

    please test ACD I have just one chance

  • Alan -

    Can some one test A&C?

  • Alan -

    could anyone test ACDE??

  • Alan -

    ACDE is correct. I tested it

  • Alan -

    i tried ACDE ... it is correct.
