Connelly cuts a solid object in half. What happens to the mass, volume, and density of the object that Connelly cuts? A)The mass and volume are both divided by two, and the density is divided by four. B) The volume is divided by two, but the mass and density do not change. C) The physical properties of the substance change, and all three properties must be re-measured. D) The mass and volume are both divided by two, but the density remains the same.

is it c?

  1. DrBob222

    not c.

  2. malia

    b?

    I think it is D.

  4. DrBob222

    Are you guessing?
    Think about it.
    If you cut a piece of wood in the middle, what happens to the mass of each piece? What happens to the volume of each piece? Now the density of the wood is g/volume. You've changed the grams (to 1/2) and you've changed the volume (TO 1/2), what about the density?

  5. PLEASE help

    d?

  6. malia

    then its d?

  7. DrBob222

    d it is.
