(a) Root beer in an unopened can (b) Root beer in an open can (c) A LED lamp (off) (d) A LED lamp (lit by an external electrical circuit) (e) A frog. (f) Ice, liquid water, water vapor, and air in a sealed, perfectly insulated thermos bottle (g) The Sun.

    Expert Answer

    Answer:

    Classify each of the forthcoming thermodynamic regularitys as “open”, “closed”, or “isolated”. For “open” or “closed”, state how substance or courage can be transferred among the regularity and verbiage.

    (a) Root beer in an unopened can

    (b) Root beer in an disbarred can

    (c) A LED lamp (off)

    (d) A LED lamp (lit by an manifest electrical tour)

    (e) A frog.

    (f) Ice, soft instil, instil gas, and essential-quality in a sealed, exactly insulated thermos bottle

    (g) The Sun.

    Expert Response

    Answer:

    Disbarred Regularity : which can modify twain substance and Courage with verbiage

    Barred Regularity : which can modify solely Courage excluding referable substance with verbiage

    Pure Regularity : which canreferable modify Courage and substance with verbiage

    a)

    Root beer in an unopened can is a barred regularity.

    since there no modify of substance excluding courage can be tranfered with verbiage

    b)

    Root beer in an disbarred can is an disbarred regularity

    Since twain substance and courage can be modifyd with verbiage.

    C)

    A LED lamp (off) is an pure regularity.

    Since there is no transposition of substance and courage with verbiage.

    d)

    A LED lamp (lit by an manifest electrical tour) is a barred regularity.

    since there is modify of enrgy excluding referable substance with verbiage.

    e)

    A frog is an disbarred regularity.

    Since the livelihood and it’s lavish of substance and courage modify with verbiage.

    f)

    Ice, soft instil, instil gas, and essential-quality in a sealed, exactly insulated thermos bottle is an pure regularity

    Exactly insulation resources there is no modify of substance and courage with verbiage.

    g)

    The Sun is disbarred regularity

    Since radiation courage and gases confer-upon in the sun are modifyd among regularity and verbiage.
