Because lighter and heavier refer to an objects weight - which has nothing to do with density ! For example - a kilo of feathers is heavier than half a kilo of lead - but lead is more dense !
7.3 = 7.30 is bigger than 7.25
The substance that is 7.5 times heavier than water when equal volumes are compared is mercury. Mercury has a density about 13.6 times greater than water, making it significantly heavier for the same volume.
it is heavier
its because when you burn something, its also known as 'oxidizing' it, and this adds oxygen to the chemical, therefor sometimes giving it more weight!
No, atomically Iron is a heavier element

Lighter and heavier are relative terms that lack specificity and precision in measurements. They do not provide enough information about the actual weight of an object in comparison to a standard unit of measurement. In scientific or technical contexts, using precise measurements or numerical values is preferred for accurate communication.
Sand is much heavier than grit. Sand should be used if you're trying to weigh something down.
That process is known as nuclear fusion. In nuclear fusion, lighter elements such as hydrogen combine to form heavier elements, releasing energy in the process. This is the process that powers stars like our sun.
By weighing the thing or multiplying the thing.

If you had the same volume of each material, lead would be heavier (something on the order of eleven times heavier!) than the same volume of water. That's because lead is more dense than water.
No... The weight is constant, unless you cut off a piece or added something to the can...
If you weigh a piece of steel, and then allow it to rust and weigh it again, it will be heavier by a small amount. The difference will be the weight of the oxygen atoms that have become bound to the iron molecules.
Um... thicker cardboard? This question is way too vague to answer.
7.3 = 7.30 is bigger than 7.25
That would depend on the wall thickness everything being equal cast is heavier
