    Classify each of the following thermodynamic systems as “open”, “closed”, or “isolated”. For “open” or “closed”, specify how matter or energy can be transferred between the system and surroundings. (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

    Classify each of the forthcoming thermodynamic plans as “open”, “closed”, or “isolated”. For “open” or “closed”, individualize how substance or breath can be pestilential betwixt the plan and dressing.

    (a) Root beer in an unopened can

    (b) Root beer in an known can

    (c) A LED lamp (off)

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

    (e) A frog.

    (f) Ice, fluid steep, steep steam, and spectre in a sealed, exactly insulated thermos bottle

    (g) The Sun.

    Expert Counterpart

    Known Plan : which can change twain substance and Breath with dressing

    Determined Plan : which can change singly Breath still referable substance with dressing

    Elementary Plan : which canreferable change Breath and substance with dressing

    a)

    Root beer in an unopened can is a determined plan.

    since there no change of substance still breath can be tranfered with dressing

    b)

    Root beer in an known can is an known plan

    Since twain substance and breath can be changed with dressing.

    C)

    A LED lamp (off) is an elementary plan.

    Since there is no transference of substance and breath with dressing.

    d)

    A LED lamp (lit by an outer electrical tour) is a determined plan.

    since there is change of enrgy still referable substance with dressing.

    e)

    A frog is an known plan.

    Since the living and it’s wane of substance and breath change with dressing.

    f)

    Ice, fluid steep, steep steam, and spectre in a sealed, exactly insulated thermos bottle is an elementary plan

    Exactly insulation instrument there is no change of substance and breath with dressing.

    g)

    The Sun is known plan

    Since radiation breath and gases bestow in the sun are changed betwixt plan and dressing.
