It usually has greater capacity for fuel storage.
Yes.
No, lighter. Two pounds is 32 ounces.
No, 30 gauge PVC is not heavier than 18 gauge PVC. In fact, the gauge number is a measure of thickness, and as the gauge number increases, the material becomes thinner and lighter. Therefore, 30 gauge PVC, being thinner than 18 gauge PVC, will be lighter in weight.
The answer depends on whether you simply wish to identify the different apple or whether you also want to know whether it is heavier or lighter than the others. The question is, therefore, underspecified.
Individual atoms may be heavier or lighter. Also, the spacing between atoms may vary.
heavier because they are two different weights
Helium is lighter than air
LIGHTER
tungsten is more more heavier han the lead as it has great mass in less volume
Just, simply, Lighter than Air Vehicles are lighter than air, so that makes them fly, and Heavier than air vehicles are heavier than air, but they use airfoils on the wings to fly.
rhenium
hydrogen
One is lighter and the other one is heavier. :D
Nitrous Oxide is heavier than air.
Tritium is lighter than deuterium. Tritium is a hydrogen isotope with one proton and two neutrons, making it heavier than regular hydrogen but lighter than deuterium, which has one proton and one neutron.
It is way lighter than after you start eating it
Heavier but safer. Look what happened to the Hindenburg:(
