It depends on how much water there is . You will have to know how much the object you are going to put in weighs.
the volume of the instrument
I have a marker which float in water.
no the shape of a substance does not determine if it will sink or float. The density of the substance determines if it will sink or float. If the object weighs more than 1.0 g it will sink. If it weighs less than 1.0 g it will float.
A needle sink in water.
a balloon float on water
the volume of the instrument
no they dont float like normal people
they put it in water???
If the density of an object is lower than water then it will float, if the density is higher it will sink.
I have a marker which float in water.
A short piece may be supported by the surface tension of water, but a coil of copper wire would sink.
no the shape of a substance does not determine if it will sink or float. The density of the substance determines if it will sink or float. If the object weighs more than 1.0 g it will sink. If it weighs less than 1.0 g it will float.
If it is in water, the density for water is 1. If the object is less than 1, it will float. If it is more than more, it will sink. To find the density, you do mass divided by volume.
does Arsenic float or sink
it will float as long as it is not fully covered water.
The mass of an object alone is not enough to determine whether it will float in water. You need to know the object's mass and its volume; in other words, its density. A kilogram of solid lead will sink in water. A kilogram of styrofoam will float. If an object is less dense than water it will float; if it is denser it will sink.
scoria will sink but pumice will float.
