Yes, the sun's mass remains relatively constant over short time scales, such as seconds. The sun's mass is so massive that the amount of matter it gains or loses in a second is negligible. In the long term, the sun does lose mass through the process of nuclear fusion in its core.
The mass remain unchanged; this is the law of mass conservation.
The mass remain unchanged, only the density is variable.
The total mass remain unchanged.
Yes, when water evaporates, its mass does not decrease. The water molecules simply change from a liquid state to a gaseous state, but the total mass of the water remains the same.
All matter has mass. Conserving matter means that you are conserving mass.
The total mass remain unchanged but each piece has its mass.
The mass remain unchanged.
The mass remain unchanged.
The mass remain unchanged; this is the law of mass conservation.
The mass remain unchanged, only the density is variable.
The total mass remain unchanged.
The mass of the object remains unchanged, as it depends only on the amount of matter in the object.
The amount of mass does not change. The energy contained by the fixed mass increases.
In a chemical reaction, the total number of atoms of each element remains the same before and after the reaction. This is known as the law of conservation of mass. Additionally, the total charge in the reaction should also remain the same.
The total mass remain unchanged.
The mass of the balloon and its contents would be unchanged.
To maintain acceleration, both mass and force must remain unchanged. Decreasing mass and/or increasing force will increase acceleration.
