If an object floats in a beaker as shown assuming the graduated cylinder was empty when the object was placed in the beaker and the beaker was full to the level of the spout what must be true?
stop cheating on gizmos, fool. :)The Answer: The mass of the water in the graduated cylinder is equal to the mass of the object.lol
What is the density of an object with a mass of 5g that when placed in a graduated cylinder raises the volume of water from 30mL to 45mL?
If the object is fully immersed then density is (5)/(45-30) = 5/15 = 1/3 gm per mL (and since it is less than 1 the density of water, is it fully immersed without something holding it down?)
How can you calculate the volume of an irregularly shaped object?
If the object in question is water proof, and small enough. You can measure the amount of displaced water when it is placed in a tank full of water, this may not work for a lot of things but it can help when attempting to measure some objects.
How does density affect the floating and sinking of objects?
An object will float if it has less density than the fluid in which it is placed; if the object has more density, it will sink.
How can you use density to determine whether an object wil float or sink in a fluid?
If the density of the object is less than the density of the water it is placed in, the object will float and vice versa.

What happens if an object of higher density is placed in water?
Higher than what ?? If the object's density is higher than the density of water, then the object sinks in the water.
When a rock is placed in a graduated cylinder containing water the height of the water will what?
remain the same
A piece of metal with a mass of 163 g is placed in a 50 mL graduated cylinder The water level rises from 20 mL to 36 mL What is the density of the metal?
The volume of the piece of metal is measured by the difference in the volume of water in the graduated cylinder before and after the piece of metal is placed in the cylinder. This is stated to be 36 - 20 = 16 mL. Density is defined to be mass per unit volume. Therefore, for this piece of metal the density is 163/16 = 10 g/mL. (Only two significant digits are justified, because the is the number of significant digits in the limiting datum 16.)
What will happen to an object placed in water if the object's density is less than the density of water?
We both know it floats
How does density affect the floating and sinking of objects?
An object will float if it has less density than the fluid in which it is placed; if the object has more density, it will sink.
What object placed in a liquid of greater density will do this?
an object will float on a denser liquid
How do you know an object has a density greater than water?
If an object placed in water sinks - then it has a density greater than water.
How can you use density to determine whether an object wil float or sink in a fluid?
If the density of the object is less than the density of the water it is placed in, the object will float and vice versa.
In order for an object to sink when placed in water the object's average density must be less?
no
