When water freezes, its volume increases by 9.05% (that is, ΔV V0 = 9.05 ✕ 10−2). What force per unit area is water capable of exerting on a container when it freezes? (It is acceptable to use the bulk modulus of water in this problem.

2.0×10⁸ N/m².

Explanation:

Bulk modulus, B is defined as the ratio of the infinitesimal pressure increase to the resulting relative decrease of the volume

B = -V₀ * (Δp/ΔV)

Given:

ΔV/V₀ = 9.05×10⁻²

Bw = 0.22×10¹⁰

Δp = -B * (ΔV/V₀)

= (0.22×10¹⁰) * (9.05×10⁻²)

= 2.0×10⁸ N/m².

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
