Shontal compared some of the properties of a marble to a piece of wood. She placed a marble and a piece of wood in a bucket filled
with water. Shontal observed the wood floating on top of the water,
but the marble sank to the bottom of the bucket. Which statement
best explains why the marble and piece of wood acted differently in
the water?

I can't see your answer choices, but it would be something that related to density of the marble vs. wood.

Explanation:

Density is mass divided by volume. A marble with a greater density than water will sink, and wood with lower density than water will float.

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).

idk what the question is about
