How does the density differ between a glass and a plastic cup that have almost exactly the same volume?

Higher molecular interaction force contribute to higher density.
In additional, higher molecular weight give tendency to higher density at same intermolecular force.
Even plastic had different density, some plastic is lighter than water but some can be twice heavy, PVC for example.

What happens if a pure substance is exactly at its melting point?
it "sweats" almost like melting plastic on a Bunsen burner, like how small droplets form just before the whole pen melts.
Will plastic bags melt when heated?
Yes. Almost any plastic will melt when heated.
Does density change if some of the liquid evaporates between the time the liquid is delivered to the beaker and to the time it was measured?
Whether or not the density changes if some of the liquid evaporates between the time the liquid is delivered to the beaker and the time it is measured depends on the liquid. For almost all liquids, the answer is no because there was not enough time. Water will have a density of approximately 1 and if a small amount evaporates, it will still have the same density. If you had the beaker at 100C and the room at 0C and waited until the water was 4C, it would make a difference. If the water was at 40C and the room was at 30C, it would almost make no difference. A very few substances would undergo tremendous cooling. That would bring a corresponding increase in density.
What does a cubic yard of average moisture snow weigh?
The density of snow is variable. Wet snow or firn has a density which is almost 10 times that of freshly fallen flakes. Depending on its densit, a cubic yard of snow could weigh between 6700 poundals and 53800 poundals.
Why does the testes differ in size?
Almost no human body is exactly symmetrical
Is Lead the smallest element?
No. Hydrogen is the atom that has the smallest dimensions. The element with the greatest density (mass per volume) is Osmium - about 22,6 grams per cubic centimeter- (Lead has a density of about 11,34 almost exactly half the density of Osmium)
How many miles between Kinbuck perthshire and Dalwhinnie as the crow flies?
50 miles almost exactly!
The distance between brunswick Georgia and atlanta Georgia?
Almost exactly 300 miles to the center of Atlanta.
What material is used to make a DVD?
The base layer is polycarbonate plastic. Then an aluminium layer is sandwiched between this base layer and a protective (clear) acrylic coating.
'what does density have to do with the ability to float?
the ability to float with density is almost impossible
What is the mass of a liter in kilograms?
Quite sure it's still being debated as water can change in density. Water at around 4 degrees Celsius is said to be almost exactly 1KG.
Why do we think there is a connection between Egyptian pyramids and the sun's ray?
I think it's because they almost exactly line up
What is the halfway point between wilmington Delaware and Tampa Florida?
If you take I-95, then Florence, SC is almost exactly half way.
What happens if a pure substance is exactly at its melting point?

Will plastic bags melt when heated?
Yes. Almost any plastic will melt when heated.
Is density the same thing as specific gravity?
Almost, but not quite. 'Specific gravity' is the density of a substancecompared to water.Numerically . . .Specific gravity of a substance = Density of the substance/Density of water.
Where can one buy plastic playing cards?
You can buy plastic playing cards at many different stores. You can buy plastic playing cards at almost any convenient store. Plastic playing cards are very common and are available almost everywhere.
