Consider three different liquids E, F,G
E=1.51g/cm3
F=1.75g/cm3
G=0.84g/cm3
In which of the above liquids would an object of mass 500g and volume 3000cm3
i.sink? ii.float?
You are right. So it floats if d is < d of liquid; sinks if > d of liquid.
I think you first have to find the density of the object which is 500g/3000cm3= 0.167g/cm
Yes
To determine whether an object will sink or float in a liquid, we need to compare the density of the object and the density of the liquid. If the density of the object is higher than the density of the liquid, it will sink. If the density of the object is lower than the density of the liquid, it will float.
i. To determine in which of the liquids (E, F, or G) the object would sink, we can compare the density of the object to the densities of the liquids. The density formula is:
Density = Mass / Volume
For the object:
Mass = 500g
Volume = 3000cm3
Calculating the density of the object:
Density of object = Mass of object / Volume of object
Density of object = 500g / 3000cm3
Let's calculate the value:
Density of object = 0.1667 g/cm3
Now, we compare the density of the object with the densities of the liquids:
Density of liquid E = 1.51 g/cm3
Density of liquid F = 1.75 g/cm3
Density of liquid G = 0.84 g/cm3
Since the density of the object (0.1667 g/cm3) is lower than the density of liquid E (1.51 g/cm3), it will float in liquid E.
ii. Similarly, let's compare the density of the object with the other two liquids:
Density of object = 0.1667 g/cm3
Density of liquid F = 1.75 g/cm3
Density of liquid G = 0.84 g/cm3
Since the density of the object (0.1667 g/cm3) is lower than the density of both liquid F (1.75 g/cm3) and liquid G (0.84 g/cm3), it will float in both liquid F and liquid G.
To summarize:
i. The object will sink in neither liquid E, F, nor G.
ii. The object will float in all three liquids E, F, and G.
