Why might a 1990 coin have higher mass than a new one?
The difference in mass between a 1990 coin and a new one is negligible for all practical purposes, unless the currency has been redesigned. (For example, in the early 1990's the UK issued new 5p and 10p coins to replace much heavier old coins.)
Does air have a lower mass than a brick?
Yes, stop trolling
Why do ice cubes float at the top of the water?
The density of ice is lower than that of water. As a result a block of ice, if wholly submerged in water, would displace a mass of water greater than its own mass. The difference between these two masses provides the upward buoyancy.
Why do egg float on oil?
Because eggs have a lower density than oil! Density is the mass divided by volume.
Will an object with a greater density have a greater gravitational pull than one with the same mass?
No. Mass and density are two different measures. An object can have more mass and less density. One pound of water in a gallon space has more mass than 1/2 pound of water in a quart space. The the quart space will be more dense 1/2 pound per quart however than the 1 pound per 4 quarts in the gallon.

Which property of a coin is different on the moon than it is on earth?
Mass
What has a lower atomic mass cobalt or nickel?
Interestingly, nickel has a lower atomic mass (58.693) than cobalt (58.933), even though cobalt has a lower atomic number (27) than nickel (28).
What was health like in 1990?
The obicitey rate was lower than it is now.

Why would old coins have a lower mass than new ones?
Many countries have changed their coin compositions over the years. The reasons can be due to metal changes, size changes, etc. Another reason is that circulation will wear down a coin, so that an older specimen actually has slightly less metal on it than when it was new.
Why a mass of lead heats up faster than an equal mass of aluminium?
It has a lower specific heat capacity
Why does nitrogen have a lower boiling point than bromine?
nitrogen has lower mass and weaker molecular forces of attraction
Which halogen has a greater mass then sulfur but lower mass than iron?
Sulfur atomic mass: 32 a.m.e.Chlorine atomic mass: 35.5 a.m.e.Iron atomic mass: 56 a.m.e.
What is the value of a 1990 quarter?
The value of a widely circulated 1990 quarter is 25 cents. Unless it is a rare, uncirculated coin, it will not be worth more than face value.

Is a coin more dense than water?
The formula for density is mass divided by volume. If the mass of something increases, the volume will increase by the same degree, so no, a coin (or any object) will not differ in density because it has a larger mass.
