a) When a submarine dives to a depth of 500 m, how much pressure, (in Pa) must it's hull be able to withstand? b) How many times greater is this pressure than the pressure at the surface. Recall pressure at the surface is atmospheric pressure at sea level which equals 14.7 psi (101 kPa). Hint when determining how many times greater remember How many times greater factor = BIGGER/ smaller)

The variables for this experiment include mass, volume and the materials in the various balls, as well as their densities. in part iii, you will be investigating the questionable baseball. use the drop-down menus to complete the sentences and identify the independent and dependent variables. in part iii, the independent variable, the one that is intentionally manipulated, is . in part iii, the dependent variable, the one that you measure the response in, is

Molten iron fills a mould, which has a volume of 200 cm cubed. calculate the volume when the iron cools and solidifies.

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference
