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.

Will an empty container increase in mass when heated?

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.


What happens if a substance of unknown composition is heated in a sealed container As a result the mass of the container and its contents?

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.


What happens to a gas's mass when it is heated?

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.


Will changing the volume of a container filled with gas change the mass of the gas?

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.


When copper is heated strongly in an open dish its mass will?

remain constant as no mass is lost or gained during a physical change like heating copper.


What happened to the mass of an object when it is cooled?

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).


Which property of a block remains constant when the metal is heated?

Mass


How would mass change if you place a burning candle in a sealed container?

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 what happens in mass volume and weight?

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.


What is the formula of conservation of mass?

Total mass = constant or: Change of mass = 0


Does your mass change on a space craft?

No. Mass always remains constant


When mass and volume change what happens to the density?

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.
