It would stay the same unless some atoms escaped.

Why does the mass change when the container is not heated to constant mass?
because energy equals mass times speed of velocity squared, if an object has greater energy, that energy can also format into mass, a cold object weighs less than the same object that is hot.
Do object with more mass accelerate faster than object with less mass?
No. If an object is being pushed with the same force, the acceleration will be lower if the mass of the object is higher. If the question refers to an object falling due to gravity, then the force is proportional to the mass. As the mass increases, so the force of gravity also increases and the acceleration will remain the same.
How can an object with the most mass be the least dense?
An inflated hot-air balloon has much more mass, but is much less dense, than a 5-pound bar-bell. As a matter of fact, so is an aircraft carrier ... it floats, but the bar-bell sinks.
How does temperature increase or decrease?
Temperature is the average Kinetic energy of molecules in an object. A hot object has more kinetic energy and a cold object has less kinetic energy.
Why hot water is more dangerous than hot air of the same temperature and mass?
hot water har less volume n surface area than hot air
What is more dense a cold object or a hot object?
A cold object is more dense.
How does heating affect an object?
The hotter an object is, the more vigorously its atoms or molecules vibrate, and in doing so generally they take up more space (the object expands). This implies that a hot object is less dense than when it is cooler (because of its volume increase)
Why does wrapping up hot things keep them warm?
Hot and cold are caused by the same thing-heat. Cold objects contain less heat than hot ones. An object can become more or less hot through heat exchange. An object can retain heat as insulation creates heat storage.http://portlandovations.org/files/pca_offstage/study_guides/beakman_live.pdf
When does an object have more thermal energy when it is hot or cold?
Hot.
Is a mass the force per unit area applied on the surface of an object?
No. If it were, then you could change the mass of an object by pushing harder on it. You can't. Mass is a characteristic of the object. Nothing outside of the object changes its mass. It doesn't matter whether the object is hot or cold, moving or still, in a rocket ship or in your sock drawer, out in the hot sun or at the bottom of the swimming pool, on earth, on the moon, or in space, the object's mass doesn't change. (Until it gets moving at a speed near enough to the speed of light, but we're not going there.)
Why does the mass of an object get smaller after it gets burnt?
Because the smoke you see during the burning, and the hot gases that you don't see, carry part of the mass away from the object.
Why do hot air masses rise over cold air masses?
Hot air has less mass which make it less dense, thus allowing it to rise over a cold air mass.
