2)What is the weight density of water(lb/ft3 or N/m3)? 3)Explain the behavior of layers in the density column in relation to their specific gravities.

4)Calculate the mass density of a 2kg object with a volume of 0.00465 m3

5)Which substance in the chart on slide #5 has a density close to this?

6)Using that substance's density(from 4 and 5) calculate the specific gravity.

7)Would this substance sink or float in water? Explain why?

I don't knowI don't knowplz give me brainliest

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
