Which of the following statements is true? the weight of a column of seawater 1 m2 in cross section and 10 m high is about 2.00×105 n. the weight of a column of seawater 1 m2 in cross section and 10 m high plus the weight of a column of air with the same cross section extending up to the top of the atmosphere is about 2.00×105 n. the weight of 1 m3 of seawater at 10 m below the surface of the ocean is about 2.00×105 n. the density of seawater is about 2.00×105 times the density of air at sea level.

“The weight of a column of seawater in cross section and 10 m high + the weight of a column of air with the same cross-section elongating up to the top of the atmosphere is about ” is true from the above-given sentences.

Explanation:

It depends on if you are talking about gauge pressure or total pressure. The “weight of a column” of seawater in “cross section” and 10 m high is about . This is gauge pressure, which considers the surrounding air pressure, and only reads off pressure above “air pressure”. “The weight of a column of seawater in cross section and 10 m high + the weight of a column of air with the same cross-section elongating up to the top of the atmosphere is about ”. The “total pressure”, which considers the “pressure” of the whole which is above a certain height.

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
