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.
No, an empty container will not increase in mass when heated. Heating an empty container will not create additional matter within the container to increase its mass.
If a substance of unknown composition is heated in an open container will Its mass will stay the same as a result the mass of the container and its contents decreases. A substance of an unknown composition is heated in a sealed container the mass of the container and its content remains the same.
No, changing the volume of a container filled with gas will not change the mass of the gas. The mass of the gas remains constant unless gas is added or removed from the container. Changes in volume only affect the pressure and density of the gas.
Mass
Mass is conserved. This means it remains constant.

The atoms in the mass become more energetic and create more pressure. If the bounds of the container allows it, such as in a balloon, the gas will expand. If the bounds doe not allow it, such as in a fixed container, the pressure will increase.

remain constant as no mass is lost or gained during a physical change like heating copper.
Nothing happens to the mass when its cooled (or heated).Mass is the same (law of Conservation of Mass).Volume can change, though, which affects density (since mass is constant).
Mass
The mass would remain the same. In a sealed container, the products of burning (such as soot and water vapor) are not able to escape, so the mass inside the container would stay constant due to the law of conservation of mass.
When a substance is heated, its mass remains constant because mass is a measure of the amount of matter present, which does not change during a physical change like heating. Volume may expand due to thermal expansion, where the particles move farther apart. Weight may appear to change due to differences in gravitational force, but the actual mass remains the same.
Total mass = constant or: Change of mass = 0
No. Mass always remains constant
When mass increases and volume stays constant, the density increases. When volume increases and mass stays constant the density decreases. When they both change, then the density will depend on the rate of change of mass and the rate of change of volume.
