The weight of an empty jam jar can vary depending on its size and material. On average, a small empty jam jar may weigh around 100-200 grams, while a larger jar may weigh 300-500 grams.
The amount of water in the jar affects its weight, which in turn affects its momentum and ability to roll. More water increases the weight of the jar, making it harder to move and decreasing the distance it can roll.
No, a jar of water will not float to the bottom of a bucket of water. The jar will sink to the bottom due to its weight and density compared to the surrounding water.
Yes, it is recommended to cool jam down slightly before packaging to prevent condensation buildup and ensure that the jars seal properly. Cooling the jam helps to avoid thermal shock, which can lead to jar breakage or a failed seal. Allow the jam to cool for about 5-10 minutes before transferring it into jars for packaging.
The jar, much like massive ships on the ocean, displaces the water and thus it floats. The jar doesn't even need to be sealed--but it does have to remain upright so it doesn't tip over and fill with water. You can imagine the water that is being displaced pushing upward toward the jar to to keep it afloat despite the jar's weight. Another factor that may be playing a part in this is that in a sealed jar, much like an inner tube at the pool, the air inside is less dense than water. The general rule of physics, in this case, is that less dense objects are "lighter" than those of more dense objects--the relative densities of the two things (water and the jar filled with air) would determine which object rises to the top.

I think jam is sold by mass/weight rather than volume, but if you want to measure the volume, a typical jam/jelly jar is less than 1 liter, so use milliliters to measure volume.
The contents of the jam jar is usually around 145 grams (i.e. not including the weight of the jar). This is usually because (although jam is a preserve, when it is made industrially it is not boiled to the extent that it would be when homemade, so is less "preserved" than it used to be), jam is not as long-life as it used to be. It is advised that it is kept in the fridge, so a 145g jar is usually the right size to fit in the fridge door.

Check for jam jar labels in the canning section of any hardware or grocery store.
That is a 4 oz jar of jam.
It depends upon the material of which the jar is made. If it is made of glass, as virtually all jam jars are, it is not biodegradable.

Jam contains a high proportion of water, so it would depend on the physical strength of the jar. I'm assuming that this is a glass jar? Most likely, the jar would crack or shatter as the pressure around it was decreased, allowing the water in the jam to boil off into the vacuum.

It weighs as much as the jam inside the jar and the jar itself. These weights depend upon the quantity of jam (often 1 lb or 454 g, but other sizes are available) and the material and size (dependant on the quantity of jam inside, and the jar shape) of the jar. eg the jar of Sainsbury's (other supermarkets are available) 340g strawberry jam weighs about 210g meaning: 1 jar of the strawberry jam weighs 340 g + 210 g = 550 g in total (when full).
