It is known that the volume of a shot is 1000 cubic meters, and the mass is 5.65kg. Try to judge whether the shot is solid or hollow? If it is hollow, the hollow part will be broken The volume should be cubic centimeter

It is known that the volume of a shot is 1000 cubic meters, and the mass is 5.65kg. Try to judge whether the shot is solid or hollow? If it is hollow, the hollow part will be broken The volume should be cubic centimeter

The density of shot put is 5650g / 1000cm3 = 5.65g/cm3
The density of lead is 11.34g/cm3, so the shot is hollow
The volume of the hollow part is V and the air density is 0.00129g/cm3
Then V × 0.00129 + (1000-v) × 11.34 = 5650
The solution is v = 501.82cm3

The mass of a hollow shot put is 27g. If the hollow part is filled with water, the total mass is 43g. What is the volume of the shot put?

The volume of this material is: V lead = m lead △ ρ lead = 27g △ 11.3g/cm & # 179; = 2.4cm & # 179; the volume of the hollow part is equal to the volume of water: V air = m water △ ρ water = (43g-27g) △ 1g / cm & # 179; = 16cm & # 179; the volume of the shot: V ball = V lead + V air = 2.4cm & # 179

The mass of a hollow shot is 27g, and the total mass of the hollow part is 43g after it is filled with alcohol

43g-27g = 16g, this is the mass of alcohol. Assuming that the density of alcohol is t (g / cm ^ 3), the density of different kinds of alcohol will be different, depending on your situation. Volume = mass / density, the volume is 16 / T (cm ^ 3)
