Astudent wanted to obtain a very accurate value for the volume of a piece of steel. he filled a 100.0 cm3 graduated cylinder to the 50.0 cm3 mark with water. after he carefully dropped the steel into the cylinder, the water level rose to the 55.6 cm3 level. he reported the volume of the steel as 5.6 cm3. how could the student improve the reliability of his analysis?

Adiver named jacques observes a bubble of air rising from the bottom of a lake (where the absolute pressure is 3.50 atm) to the surface (where the pressure is 1.00 atm). the temperature at the bottom is 4.00 ∘c, and the temperature at the surface is 23.0 ∘c.what is the ratio of the volume of the bubble as it reaches the surface (vs) to its volume at the bottom (vb)? if jaques were to hold his breath the air in his lungs would be kept at a constant temperature. would it be safe for jacques to hold his breath while ascending from the bottom of the lake to the surface?
