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.

Will a jar of water float to the bottom of a bucket of water?
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.
Why a sealed bottle partially filled with a liquid can float?
A sealed bottle partially filled with a liquid can float because the weight of the liquid inside the bottle is less than the weight of the liquid it displaces. This creates an upward buoyant force that allows the bottle to float.
Why an empty glass bottle with a sealed cap float on water?
An empty glass bottle with a sealed cap floats on water because the air trapped inside the bottle provides buoyancy. The air in the bottle is less dense than water, causing the bottle to float on the surface. The sealed cap prevents water from entering the bottle, maintaining its buoyancy.
What are examples of a vacuum?
Examples of vacuums include the vacuum inside a sealed jar, the vacuum of outer space, and the vacuum inside a vacuum cleaner.
How do you make a car float on water?
The car openings all need to be properly sealed to prevent water entry to the car body and then many cars will float. There are numerous holes and seams in the car body that are plugged and sealed but not sufficiently to prevent water entry.
What is a sentence for sealed?

Will a jar of water float to the bottom of a bucket of water?
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.
What happens when you put ice cold water into a sealed jar?
The jar can not handle the temperature and compression so it cracks.
1 If you have a balloon with a fixed amount of air in a sealed jar at room temperature balloon does not fill the entire jar You place the jar in a pan of boiling The water?
As the water boils, it creates steam which increases the pressure inside the sealed jar. This increased pressure causes the air inside the balloon to expand, filling more of the jar.
What would heating a sealed glass jar do?
Increase the pressure of the gas inside

Can water evaporate in a sealed jar?
