Question

Can someone please answer these questions? It would be greatly appreciated

2. On Figure 1, 100g stainless steel standard (density 8.0 g/cm2) is balanced with 100g water (density 1.0 g/cm in air atmosphere, STP a) Which substance will displace more air? b) Which substance will appear heavier in vacuum? 00.3 0 100.0009 100.000g Figure 1: Buoyancy effect.

Answer 1

2)

a)

denisty of stainless steel = 8.0 g/cm3

volume of steel = 1100 / 8 = 137.5 cm3

density of water = 1.0 g/cm3

volume of water = 100 cm3

here density of stainless steel is more denser than water.

so stainless steel will displace more air

b)

actually steel is more heavier than water .

but in vacuum , and no air resistance . both fall in same time.
